General service ball valve for low pressure applications

ASME 600 Class: General Service

The G-Series valve is a general service, uni-directional ASME 600 Class full-bore valve for drain and vent applications with clean, low-pressure steam, gas or liquid. The floating ball design with metal/graphite laminated seats lower torque and actuator requirements.
