Parallel Slide Gate Valve Manufacturer | Industrial Parallel Slide Gate Valve Supplier
ZONCIC is a professional parallel slide gate valve manufacturer in China, supplying high-quality industrial gate valves for oil & gas, petrochemical, power generation and industrial pipeline systems. Our parallel slide gate valves are designed for reliable shut-off performance, low friction operation and long service life in demanding service conditions.
What is a Parallel Slide Gate Valve?
A parallel slide gate valve is a type of gate valve that uses two parallel discs or gates to achieve shut-off. Unlike wedge gate valves, parallel slide designs reduce friction between seating surfaces and are well suited for applications involving high temperature, steam and thermal cycling. They are widely used in power plants, petrochemical systems and industrial pipelines where reliable sealing and operational stability are required.
