Column Drain Valve
The Y-body and poppet-in-cage design result in a robust valve with a well-supported poppet, which permits throttling at 25 MPa. This allows the valve to be used for pipe filling and flushing. It also provides for slow and gentle opening and closing and thereby eliminates pressure surges (water hammer).
The valve is also available in an angle pattern format.
The purpose of the Isolation Valve is to isolate flow in the forward flow direction at pressures up to 25 MPa.
It can be used as a manual isolation valve with a simple hand-wheel. Alternatively, it may be controlled with high-pressure water or an electric actuator and used as a control valve. For example, because the valve is capable of throttling, it can be used as a pump control valve or pressure sustaining valve. Many other applications and control configurations are possible.
Valves over 50NB are fitted with reverse flow protection and therefore will also isolate in the reverse direction.
