Manual operation of the valve is accomplished with a 7-position notched detent plate and spring-loaded lever assembly. Automated Operation is achieved by assembling any pneumatic or electric quarter-turn actuator control package to the stem, using a properly fitted coupling and bracket. Tapped mounting holes are provided for assembling the bracket to the valve.

Maximum working pressure for all sizes is 125 psig. Operating temperature is -40 to 275ºF depending on the elastomer system used in the valve. For throttling applications, proper valve sizing involves determining the Cv required, taking into consideration fluid viscosity, pipeline size and cavitation potential. Consult Factory for sizing verification.
