Valves

Choosing the right valve can be difficult.  The sheer range of valve types on the market today reflects how challenging controlling and directing bulk material flow is in a process. Each type has its own particular benefits or is designed for a specific application. 

 

The application, material characteristics, dimensioning, cleanability, maintenance and cycle frequency are all factors to take into consideration. Our process engineers can help guide you to find the best fit to your process requirements.

  • Image of Butterfly valves

    Butterfly valves

    Swissfluid’s main focus lies in the area of specialized, plastic-lined valve products that are used in severely corrosive or abrasive applications. The valves have been designed for maximum longevity and require little to no maintenance, resulting in low total cost of long-term ownership. Thanks to a modular design of variable components, they are often able to provide custom solutions using standard products. Their range of lined process valves includes butterfly valves, diaphragm valves, cone valves, ball valves, check valves, control valves and sampling valves, with sleeves available in PTFE, PTFE-AS, PFA, PVDF, ETFE, UHMWPE and PP.

    Rotary disc valves

    Everlasting’s range of diverter valves, bulk-material valves and process valves feature their revolutionary self-lapping, rotating disc-valve technology. The well-proven, rotating shearing disc construction makes their products particularly suited to highly abrasive products; the rotation of the disc in the process medium renews and polishes the metal seating surfaces with each operation. This unique concept causes Everlasting valves to wear in instead of wearing out like other valves. Everlasting valves are in operation in some of the harshest plant environments, all over the world. As the Everlasting name implies, their valves are synonymous with quality, durability, and longevity.

  • Image of Iris valves

    Iris valves

    Mucon’s range of iris diaphragm valves are known for their superb flow control characteristics and versatility. The double diaphragm design makes it ideal for in-line applications with no material leakage into the atmosphere. The iris valve is non-jamming, easy to operate and maintain, safe, gentle and strong - making it an ideal solution for a variety of different applications. The product that passes though the valve does not come into contact with moving parts. Manually operated, pneumatic or electric actuator versions are available. With a full bore diaphragm opening, there is no restriction to product flow. The iris valves are suitable for frequent operation and can handle materials up to 1600 kg/m³.

  • Image of Knife-gate valves

    Knife-gate valves

    The special sealing system on the WEY valve consists of an encapsulated edge seal and an internal transverse seal, where repacking under full pressure and without shutting down the system is possible. This, combined with the profiled knife and the self-cleaning corners made the WEY valve one of the most reliable and functional valves on the market. These high-quality valves are suitable for both liquid and dry media, including particularly abrasive media. They feature a bidirectional seal and a fully guided knife which prevents jamming. Available as handwheel, pneumatic hydraulic or electrically operated, in round, square or rectangular versions. A variety of materials are available, including exotic alloys. Special design for operation under vacuum at 100 bar.

    Swing check valves

    MEI offers an entire range of high-quality sanitary valves, which can come fully certified for pharma and food applications. With a self-centering wafer design, these light-weight, easy-to-maintain valves feature easy installation with tri-clamp connections. Available in the standard materials of zinc plated carbon steel, stainless steel 316 or alu-bronze and metal/metal seats or soft seals (NBR, EPDM, PTFE, FKM).
