Structure Features
1. There is lock pin and dust protecting cap for the valve.
2. The stem has back sealing function and packing works in non-pressure
3. It follows cold drawing stainless steel or forged stainless steel for processing production with the function of high
Temperature resinstance, High pressure resistance and fluid flushing resistant. Pressure range: 800Psi~10000Pis
4. Disc welding STL and stem is rolled. When handwheel rotates to instantaneous contact between thedisc and seat, the disc will
Not rotate with the stem any more, but move downward straight. It will not commence rotation friction between the disc and the
Seat To avoid scratching sealing faces and extend operation life.
5. Sleeve type valve is made up of clamp nut, double clamp and body. By the outisde force between body and clamp nut, double
Clamp commence radial plasticity deformation, clamp steel pipe tightly as sealing function. Clamped connection has advantages
Ofrliable connection, high sealing, high pressure resistance, anti-vibration and convenient installation and maintenance, etc.
II, ALLvalves shall be approved strictly with hydraulic test and air tightness test before the delivery.
1, hydraulic test(1.5 time pressure)according to ANSI B16.34/API598 and air sealing test(1.1 times nominal pressure)Test

Wenzhou Better Valve Co., Ltd. Was established in 2007, integrating the design, production, examination with sales into a body in the field of valve industry.
BETTER VALVE is also equipped with the test lab with examination equipment for material chemical composition analysis, physical property and non-destructive examinations such as RT, UT, MT, and PT.
