Althon PHA-G HDPE 500mm Hand stop gate is a simple manually operated valve for pipework up to 500mm diameter. Our handstop gates are design to isolate and control the flow of water discharging from pipes or to manage water levels. Manufactured in HDPE with an EPDM Seal the Hand Stop gate is available to suit 150, 200, 250, 300, 400 & 500mm Dia. openings. Above this size Penstocks are a better option because of the weight.

The maximum on and off seating pressure of a 500mm hand stop gate is equal to the height of the construction of the valve
