Wafer type butterfly valve Standard Test :
Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.
Seat Test: 1.1 times the working pressure with water.
Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
Special Test: On request, any other test can be carried out according to special instruction by client.
A valve dealer in Pakistan imports valves as inventory for sale.
Main products: American standard gate valves, stainless steel check valves, ductile iron soft-sealed gate valves, wafer butterfly valves, exhaust valves and other valves.
This valve distributor from Pakistan described some informations about their company to our sales manager of the international department.They have been engaged in the valve industry for 11 years and are very professional, with a fixed customer base and sales methods. As a middleman, they need to purchase a large number of valves that are sold every day. And China is a big valve producing country, so they intend to cooperate with Chinese valve manufacturers as their own exporter. After some comparisons, the enthusiasm form WESDOM left a deep impression on them. From the initial samples, trial orders to subsequent FCL orders, the cooperation is very smooth and pleasant. This Pakistan distributor said that the cooperation with WESDOM is very pleasant, and the products and services of WESDOM are also very considerate, and will have more cooperation with WESDOM valve in the future.
