Upwey Valve & Engineering manufactures a variety of column drain valves, designed to isolate flow in the forward flow direction at pressures up to 25 MPa.
These column drain valves can be used either as manual isolation valves with a simple hand wheel, or controlled by high pressure water or an electric actuator and used as control valves.
Valves that are rated over 50NB are fitted with reverse flow protection, and can also isolate in the reverse direction.
Constructed from a Y body and poppet-in-cage design, these column drain valves can be used for pipe filling and flushing, and also provide for slow and gentle opening and closing. This works to eliminate pressure surges.
These valves are also available in an angle pattern format, and feature:
- stainless steel poppet and seat elements
- corrosion resistant internal parts; and
- in line maintenance capabilities.
