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
