China Valmax are a part of the metal-seated ball valve. This kind of ball valve has no leakage under extreme working pressure and temperature.

 

The China Valmax metal-seated ball valve meets the toughest endurance and tightness requirements. The metal-seated ball valve Series has been through fire safety test according to DIN EN ISO 10497 and API 607. It has get certification by TUV.

 

The metal-seated ball Valve can bear 420 bar pressure (ASME Class 2,500). And can stand from -29°C to 450°C temperature range. It can even withstand even harder conditions.

 

With a double sealing system and the integral lantern ring, the ball valve  can be detected quickly if there is a smallest leak. But there is impossible for the ball valves to have leakage to the air.

 

All the ball valve parts are made of 316 stainless steel which can work under corrosive environments. The valve seat and valve ball surfaces coated with Hardalloy and carbide compounds and the double sealing system consists of premium-quality graphite sealing rings. The metal-seated ball valve Design and novel axial bearing washer can work smoothly even at high pressures.
