Two-Position Stop

Applicable Valve Types: All valves except standard range N and W

Restrictions: Not on valves in Normally Open configuration or valve Type U.

Cannot be use in conjunction with control module. 

The Two-Position Stop allows the valve to be pneumatically driven to either one of two open positions in addition to the fully closed position. The two positions provide a high degree of repeatability as they are set with a screw mechanism, ideal for fine adjustment for application such as dosing.

The Two-Position Stop can be used on mixproof valves with an axial seal arrangement (Type D, K, B) but not those with a radial seal (R, M, T, L). It cannot be used on valves that are Normally Open or those valves that stroke downwards (Type U). It is not possible to fit a control module if a two-position stop is used, although proximity switches can be mounted in the valve lantern.
