Parallel Slide Gate Valves, Pressure Seal Bonnet, Full Bore, Supplier, Price, Features

Thanks to its unique double gate structure to open and seal, parallel slide gate valve can achieve excellent two-way sealing performance under both high pressure and low pressure. The greater the torque, the tighter the seal. 

During the opening and closing process, the sealing surface of the sliding disc and the sealing surface of the seat ring are separated, which reduces the wear of the sealing surface and prolongs the service cycle of the valve. With extremely high shut-off performance, it is widely used in emergency shut-off valves and vent valves under high temperature, high pressure to extremely low conditions, such as refined oil pipelines and storage equipment, oil and natural gas extraction wellheads and pipelines with suspended particles and fiber media, independent steam turbine feed systems, high temperature and high pressure harsh working conditions with particles, etc.
