For soft sealing forged check valve we can produce it in zero leakage and the metal seated check valve we can make it according API 598 or Class D.
Application:
- Oil and Gas, water project, petroleum chemical industry, mining, power station, medicine, etc.
Products Description:
- Size: 1/2″-4″
- Pressure: 150LB-2500LB
