The Valtek® TX3 Molten Salt triple-offset butterfly valve provides concentrated solar power (CSP) plant operators with reliable performance, tight shut-off, and minimized maintenance in molten salt applications. -
Goodwin choke valves utilize solid tungsten carbide trim, therefore, minimizing the erosion of critical components, thereby providing long-term reliability of performance in severe service. With the use of “torturous path” technology, it dissipates and controls the high energy, velocity, and turbulence within its trim. Consisting of one or more concentric sleeves with specifically aligned holes in each, the trim provides controlled staged pressure reduction. Actuation Options Include: • Manual Operation • Pneumatic • Hydraulic • Electric • Electro-hydraulic -
The DrainFlow Series 051000 valve is typically used for on-off bottom drain tank applications, where flushing or fluid transfer is necessary. The valve mounts flush to the tank with a plug extending into the tank and with the seat ring flush with the inner wall of the tank. The valve’s compact, lightweight design is ideal for in-line maintenance under the tank. It can be specified with either a 45° or 60° outlet angle. Other options include bellows seal, normalising fins, a special pocketfree body, steam jacketing or a plug that retracts into the body (as opposed to the standard design with an extending plug). The tank flush valve can also be supplied as a control valve. -
The Flowserve Valtek Mark Six is a globe-style, single-seat, top-entry automatic control valve with a fabricated extension for cold box cryogenic applications to -425°F/‑218°C. Mark Six bodies are constructed of bronze or austenitic stainless steel for high impact strength at low temperature and minimum heat transfer. Mark Six is designed for high flow capacity with a minimum of mass to reduce boil-off on valve cool-down. -
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. -
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 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 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 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 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 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. -
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 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. -
