-
The Model 2100 provides ready access to storage tanks for gauging or obtaining samples. The gauge hatch may also provide additional pressure relief as a supplement for normal or emergency venting. These gauge hatches are intended for use where the fire protection afforded by flame arresters is not considered necessary. Common applications where it is commonly used includes atmospheric and low pressure tanks.
-
The 8900 Series manway pressure and pressure/vacuum relief vents provide emergency pressure relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks, as well as convenient access for tank cleaning, inspection, and repair. Emergency relief vents provide relief from excessive internal pressure which may be caused by an abnormal condition; such as ruptured internal heating coils, an external fire, a failure of the tank blanketing system, a sudden cooling of the tank or a break in the tank wall.
-
The Model 3700 manhole and emergency pressure vents provide emergency pressure relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks, as well as providing convenient access for tank cleaning, inspection, and repair. Emergency relief valves provide relief from excessive internal pressure, which an abnormal condition, such as ruptured internal heating coils or an external fire may cause.
-
The Model 8700 emergency pressure/vacuum vents provide emergency pressure and vacuum relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks, as well as providing convenient access for tank cleaning, inspection, and repair. The vacuum relief allows the intake of air necessary to maintain the tank pressure within the permissible vacuum limit to avoid damage to the tank.

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 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.

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 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.
