31D brass ball valves


The 31D is a 3-way, brass ball valve. It can be equipped with a manual handle or with direct mount pneumatic or electric actuators. The direct mount actuators eliminate the valve-actuator mounting kit, which adds unnecessary height and expense. A full range of accessory items are available including limit switches, solenoid valves, positioners and manual override devices.
