Description

High Pressure Seal Check Valve, Inch 1/2"～48" , Class900～Class 2500

Zaval high pressure seal check valve is suggested for better closure in high pressure condition, while bolted bonnet is still available for customer's option. The pressure seal design incorporates a metal-to-metal seal that becomes tighter as the pressure increases. The pressure seal valves are widely used in fossil fuel power plant. Compared with bolted bonnet valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.

  1. Only one sealing face is designed on the valve body and valve disc,
  2. Full stellite overlay seat sealing surface
