Angle Seat Valves

Angle Seat Valves

Due to their robust design, pressure actuated external-fluid valves are used in a wide variety of applications. they are used anywhere where special requirements in terms of temperature stability as well as resistance against aggressive mediums are in place, or where fluids with high viscosity and contamination have to be controlled.

The mode of operation for pressure actuated external-fluid valves is simple. a neutral control medium such as for example, air, water or nitrogen, affects the piston actuator, providing the required valve position – open or closed. in comparison to magnetic valves, pressure actuated external fluid valves demonstrate a distinctly higher closing force, can implement shorter switching cycles, and are approved for use in the ex-zone without further safeguards.

Depending on the environment and operating fluid, the valve body is available in brass (CW617N) and stainless steel (1.4408). the pneumatically operated angle seat valves have a maintenance-free piston actuator. there are two actuator sizes to select from in synthetic material, and two others in stainless steel/aluminium. Multi-part, self-adjusting ring packing seals the valve reliably and permanently against the operating fluid, ensuring high durability.

Unpleasant water hammering is a thing of the past with the automatic damped closing action, (flow direction is against the valve plate). the arrangement of the valve seat in an inclined position relative to the direction of flow also allows for superior flow characteristics.

in addition to the basic versions “normal closed” and “normal open”, numerous configuration variations are available, such as double acting with position indicator or with NAMUR connection technology. With our extensive range of accessories, a solid main valve becomes an “intelligent control valve” with the customary Buschjost quality. this allows you to control and regulate your processing safely and reliably!
