Charactors

1 Piston action seat design. According to customers’ requirements, it can be disigned to single piston action,self-release pressure seat and double piston action,dual sealing structure. The pressure auto release device should be installed in the body if the seat is designed to double pistion action. When the pressure exceed allowed pressure 1.33 times, the pressure can be released automaticly. Thus ensure running safty.

2 The ball and the seat are coated by Ni base or WC, the hardness can be higher than HRC70, it has advantages such as unti-friction and corrossion resistance.

3 The design for the seat is fully sealed type, thus the impurity cann’t enter the seat, avoid the seat being stucked, ensure the reliable safty. It adopts O-ring Or V type packing sealing structure, with the spring and medium press, the V type packing can inflate to achieve sealing.

4 The sealing for the stem are O-ring and packing. We also install a retainer in the middle. When the packing lost effect, we can inject grease to achieve emergency seal. The packing is pressed tight by the bolts, and the spring is also installed here, so when the packing lose, it can also be sealed.

5 Bellow entrance stem. Unti-blowoff ,unti-static,ensure the reliable use.


Leakage

Zero leakage when the size is less than or equal to DN100; conforming to API598 or ASME b16.04 when the size is more than DN100
