The DFS series scotch and Yoke Pneumatic Actuators are heavy-duty actuators for operating large diameter ball valves, butterfly valves, plug valves and other 90˚ rotating mechanism. Available with two yoke deigns namely symmetrical design and canted yoke design. Cylinder blocks are plated with hard chromium to increase the service life of the actuators. The piston rod and guide block connection superior surface finish and the self-lubricating bearings maximize the input energy transfer directly to the valve stem and ensure reliable operation over the service life of the actuator. Can be supplied with the complete line of controls and monitoring accessories, including hand wheel, hydraulic manual override, limit switches, solenoid valves, positioners and other control accessories. -
The Vahn-Tech Series DFS is an economic rack and pinion style pnuematic actuator, with both captured coil spring-return and double-acting configurations. With standardized accessory (VDI/VDE 3845) and valve (ISO 5211) mounting pads, packaging with Vahn-Tech and third-party valves and accessories is simplified and easy. -
The Vahn-Tech Series 4X4 packs more than double the torque of conventional rack and pinion actuators thanks to its four pistons generating torque around a centrally located pinion. With more pistons in the actuator, this allows the actuator being more compact with size reduced by more than 30% compared to double piston actuator of the same torque. With four small cylinders each located on one of four sides of the unit and at a given air pressure, the 4x4 produces the same torque output as double piston models using smaller diameter pistons and a narrower pinion. The narrower pinion allows the pistons to travel shorter distances so that they can move faster from one position to the next. -
The Vahn-Tech Series VT-OM Electric Actuators offer a range of 35 Nm to 4500 Nm torque. The actuator comes standard with NEMA 4X (IP 67) environment rating. All models are ISO 5211 compliant and have a visual position indicator. The manual override can be operated without clutch and brake. -
The Vahn-Tech Series VT-OMX Explosion Proof Electric Actuators offer torque ranges from 35 Nm to 1,500 Nm (310 in-lb to 13,280 in-lb). All models are ISO 5211 compliant and are equipped with a visual position indicator. The manual override can be operated without clutch and brake. VT-OMX series explosion-proof quarter-turn electric actuators are structured as flame-proof and combustible dust-proof. The directive and standards marking are II2GD Ex db IIB T4 Gb, Ex tb IIIC T130°C Db. They are classified as Zone 1 or Zone 2, containing Group II A and Group II B gases, Zone 21 or Zone 22, containing combustible dust atmospheres or explosive gas atmospheres and combustible dust atmospheres. Temperature group T1 to T4. -
The Vahn-Tech Series VT-S Spring-Return Fail-Safe Electric Actuators in addition to the normal function (floating control, on-off control, modulating control) are designed to provide fail-safe positioning of valves and dampers upon loss of power supply. A mechanical spring set is used to position the controlled device to either the fully OPEN or fully CLOSED position without any external power source. For ON-OFF type, a mechanical buffer is employed at the end of the spring stroke in order to reduce the dynamic effects of the spring return system. A clutch-free manual override is available as an option for standard units to provide full-time manual positioning of the valve. -

The Vahn-Tech Series VT-BV-T is an API 6D compliant and monogrammed trunnion mounted ball valve available in standard pipeline soft-seated configuration, as well as specialty metal-seated, high-temperature, acid gas and CO2 configurations. Seats designs can be configured as Single Piston Effect (SPE) and Double Piston Effect (DPE), providing verstatility to suit any application requirement for Double Block & Bleed and Double Isolation & Bleed. -
The Vahn-Tech Series VT-BV floating ball valves are designed to provide maximum service life and durability. Designed with extensive safety considerations including provision of locking devices, blow-out proof stems and prevention of misalignment of lever handles provide safe handling in the field. To ensure smooth plant operation, antistatic devices, fire safe seal design and cavity pressure relief features are provided. -
The Vahn-Tech Series VT-BV-TE is an API 6D compliant and monogrammed top entry trunnion mounted ball valve available in standard pipeline soft-seated configuration, as well as specialty metal-seated, high-temperature, acid gas and CO2 configurations. Seats designs can be configured as Single Piston Effect (SPE) and Double Piston Effect (DPE), providing verstatility to suit any application requirement for Double Block & Bleed and Double Isolation & Bleed. -
Vahn-Tech Series DOBF is a cost-effective butterfly valve solution for isolation valve applications. Providing lighter weight, smaller face-to-face, and simple quarter-turn rotary movement, a double-offset butterfly valve design is a great solution for zero-leakage isolation relative to ball valves for large sizes. With the eccentric disc designed to reduce the rubbing of the seat it drastically reduces torque requirements for actuation while extending seat life expectancy. -
The Vahn-Tech Series TOV and TOBF triple offset butterfly valves are designed to meet the critical zero-leakage isolation requirements for industry applications. Split into two primary design categories, floating and fixed seats, there's versatility in the selection to match your process requirements and project economics. -
Vahn-Tech Series LBFV is a fluoropolymer lined concentric butterfly valve designed for chemically corrosive process medias. The design features enhanced seat energizer along with mechanically loaded packing arrangement to mitigate any media propagation past the stem. -
Vahn-Tech Series 100, 200, 300 & 400 are rubber lined concentric butterfly valve designed as economic solution for lower pressure isolation applications where weight and face-to-face requirements are valued greater than the rated flow capacity. -
Vahn-Tech DC Series knife gate valves are linear shut off valves that are light weight with compact construction. Valves are available as manual with handwheel, or can be automated with pneumatic cylinder or electric actuator for remote operation. The arc shape of the gate of our knife gate valve is designed to be particularly suitable for cutting off fluid containing fiber or suspended particles. The knife gate valves are ideal for many applications in the process industries of Pulp & Paper, Wastewater Treatment, Mining, Sugar Making and Chemical Processing. -
Vahn-Tech DK Series knife gate valves are soft sealing shut off valves that are light weight with compact construction, and convenient to install and use. Valves are in full port design and with small flow resistance. When the gate is open, direct current flows between valve and pipeline. Valves can be operated manually with handwheel, or with automatic actuator for remote operation. The cone-shape design of the gates provides strong cutting force. The die-casting rubber seats are with bi-directional sealing. The main advantage of the valves is that when fully open, the medium will not flow into the valve chest, which prevents the pulp from settling in the valve chest and thus reducing the maintenance cost. -
Vahn-Tech DT Series knife gate valve is mainly intended for process control in pulp slurry, residue discharge and sewage treatment. It is especially suitable for installation with equipment such as stock cleaners, gravity separators and aqua pulper. -
Vahn-Tech DF Series square knife gate valve is mainly used as pneumatic on/off valve for process control in pulp making slurry or sewage treatment. It is particularly suitable to serve as a residue discharger on equipment such as stock cleaners, gravity separators and hydra pulper in the paper making industry. -
Vahn-Tech DB Series funnel knife gate valve is used in service as a pneumatic residue discharge valve in pulp making, paper making and sewage treatment. This type of valve is well suited for high consistency media containing solids, fiber or residue, serving as a residue discharge valve on stock cleaners, gravity separators or pressurized screens. The "funnel" at the bottom of the collects waste discharged from the valve body during the closing stroke. This greatly reduces the wear between the body and gate, and prolongs the life cycle of the valve.
