Z81X trench open stem gate valve is characterized by light switching, reliable sealing, good elastic memory and long service life. Widely used in water, sewage, construction, fire fighting system and other fluid pipeline as a regulating and intercepting device.
Product Features
- The valve seat features a flat bottom design without recesses, matching the full bore diameter of the valve body. This prevents debris accumulation, ensuring unobstructed fluid flow.
- The valve body and bonnet are coated with epoxy resin both inside and out. The valve body is thickened to prevent cracking or peeling during use.
- The valve plate surface is fully covered with rubber, which is firmly bonded to the core frame, ensuring it does not easily detach and maintaining excellent elasticity.
- The upper seal between the valve stem and bonnet employs three O-ring rubber seals, ensuring smooth stem rotation, reliable sealing, and extended service life.
- The valve body is cast to perfectly match the valve plate, ensuring excellent sealing performance and interchangeability.
