Description

Product Advantages
1、The structure is simple and compact, the rotation of 90 °is quickly to open and close, and the service life is long. The side flange can meet the PN10, PN16, 150Lb and 10K flanges;
2、All products can provide the pressure test: All Yuming  products can provide the pressure test report before leaving the factory.
3、High performance seat rubber: The rubber content is 50%, and the switch life is more than 30000 times
4、Axial seal: The shaft is supported by 4 oil-free bearings, double seal structure design of oil seal and O-ring, smaller torque and reliable seal;
5、Surface coating: Epoxy powder coating is adopted, with strong adhesion and good weather resistance. It can be used indoors and outdoors.

6、Ductile iron handle: The handle is made of ductile iron, compared with Stamping handle, ductile iron handle is more better strength, stronger corrosion resistance and much more durable. The end handle with half-round structure design, is no edges and corners and feels very good.

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.
