Forged Steel Y-Type Check Valve DN10-DN50 150LB-800LB with Internal Thread Flanged Connection for Industrial Applications
The H61Y forged steel Y-type check valve features three distinct bonnet designs to meet various application requirements:
- Bolted Bonnet Design: Valve body and bonnet connected with bolts and nuts, sealed with spiral wound gasket (316 with flexible graphite)
- Metal Ring Connection: Available for special customer requirements
- Welded Bonnet Design: Valve body and bonnet connected by threads with internal pressure self-sealing ring
This automatic check valve opens and closes based on medium flow to prevent backflow, functioning as a one-way valve and back pressure valve.
