1712 Zetco Bronze Outside Screw & Yoke Bolted Bonnet Flanged Gate Valve
A bronze flanged gate valve with integral seat and external rising screw and yoke operation. As the valve is operated, the screwed stem rises and falls with the gate, providing clear visual confirmation of whether the valve is open or closed, making it ideal for use in applications such as fire protection systems where opening or closing the valve to test it is not possible.
