The valve is direct mounted to the actuator using the international standard ISO5211 mounting pad. Rugged unique integral motor/housing design provides higher torque in a very small package. Special wave line seat and disc shape, reduces the required torque and extends the life of the valve. Precision machined 316SS disc with two-piece stem (shaft) construction, enhances the flow capacity of the valve and reduces turbulence. The stem utilizes PTFE/graphite bearings with V-ring seals preventing leakage.
Explosion proof actuator certified for UL Class I Div I as well as ATEX specifications. Two auxiliary limit switches are supplied to confirm valve open and closed position.
