Valve Test Rigs   » Valve Test Rigs for testing all types of Process Control & Safety    Relief Valves to confirm:   √ The Pressure containing capability of the valve shell   √ The Degree of tightness and pressure retaining capabilities of the     valve seat and closure mechanism.   √ The opening pressure of a safety / relief valve.

Tests Include:

√ Shell Test - Pressure inside the assembled valve to 1.5 times working pressure.
√ Back Seat Test - Pressure inside with seat fully opened & closed to 1.1 times working pressure.
√ High Pressure Closure Test – Pressure applied to each side of the closed valve to 1.1 times working pressure.
√ Low Pressure Closure Test – Same as High Pressure but with air at 100 psi (7 bar), detected by air bubble in water column.
√ Relief Valve Test – Opening Pressure using a Pop test and to 90-95 % of set pressure.

Test Rigs can be supplied with a range of clamp benches:

√ Manual Clamping
√ Hydraulic Clamping
√ Automatic PLC proportional control Hydraulic Clamping.

Other Features:

√ Hydrostatic air/gas pressure generation.
√ Size up to 20”, class 1500
