The WEIKIN VALVE Testing Department is equipped with 7 advanced test benches designed for both hydrostatic and gas testing. These facilities can handle valves ranging from ½” to 56” in size, covering pressure classes from CL150 to CL2500, ensuring precise and reliable performance verification under demanding operating conditions.
Should be performed to verify the thrust required to open, move or close the valve operator at the pressure specified by the Customer in line with project requirements (maximum pressure differential) WEIKIN VALVE has the most modern equipment of Norbar Torque equipment in House to perform such tests till 100.000 Nm

High temperature valves performance can be tested at elevated temperatures up to 660°C (1220°F) to simulate operating conditions and prove that selected material and construction are suitable for that critical application. All our operators are experienced and trained to conduct this test with appropriate safety precautions.

Can be performed to verify the electrical resistance between the valve body and the ball and between the valve body and the stem, measured using direct current power source not exceeding 12V. WEIKIN VALVE meet the AtEx 94/9/EC directive for equipment and protective systems intended for use in potentially explosive atmospheres

Is generally performed after hydrostatic testing, exception for cryogenic and low temperature applications, in those cases gas testing should be done before. High pressure gas testing has potential hazards and appropriate safety precautions are taken during gas testing performance: testing area has a suitable bunker type protection, equipped with control panels and cameras to allow the operator to perform the test in safety conditions.
Fugitive emissions are emissions released through leaks, spills, and evaporation with potential immediate hazard to human health and safety.
Production test at ambient temperature in accordance to ISO 15848-2 or Shell SPE 77/312
Type test approval in accordance with ISO 15848-1 or Shell 77/300
A Double Isolation & Bleed (Double Piston Effect seat) valve is a valve with two seating surfaces each of which provide sealing in both directions in the closed position, with a means of a cavity vent or relief valve between the seating surfaces: seats are designed to seal with pressure from body cavity. Pressure test is performed without the relief valve which should be removed if fitted, the valve and its cavity are completely filled with test fluid:
DIB-1 (both seats bi-directional) the test pressure shall apply successfully to each valve, each seat should be tested separately from the upstream side;
DIB-2 (one seat uni-directional, one seat bi-directional) the test pressure shall apply successfully to each valve end, each seat should be tested separately from the upstream side first, and then test the bi-directional seat with simultaneous pressure to the valve cavity and the upstream end.
Fluid detection shall be monitored by overflow through the cavity pressure relief connection.
