Series 32 Model 11 Parallel Slide Gate Valve

1. What is a Parallel Slide Gate Valve?

A Parallel Slide Gate Valve is a gate valve that is different from a Wedge Gate Valve. The two discs of a Parallel Slide Gate Valve slide parallel to each other on the valve seat surface, forming a tight seal to control fluid flow by fully opening or closing. Since the Parallel Slide Gate Valve has better sealing capabilities than a Wedge Gate Valve, it is often used in applications that require high pressure and temperature. In essence, the Parallel Slide Gate Valve uses fluid pressure to enhance its sealing when the disc slides to the valve seat, making the Parallel Slide Gate Valve an ideal choice for tight closing and efficient fluid flow regulation.

2. What are the advantages of the Parallel Slide Gate Valve produced by Freeman Valve?

2.1 The Parallel Slide Gate Valve produced by Freeman Valve has a wide and flat seat surface. This design allows the sealing pressure to be distributed more evenly, minimizing the impact of minor surface defects and ensuring that the parallel slide gate valve has good sealing;

2.2 The Parallel Slide Gate Valve produced by Freeman Valve has low torque. Because the sealing of the parallel slide gate valve is achieved by sliding rather than compression, the torque required to open and close the valve is significantly reduced, thereby reducing the pressure on the components and actuator.

2.3 The Parallel Slide Gate Valve produced by Freeman Valve has thermal expansion tolerance. This design allows the valve to expand thermally without affecting the seal without exerting pressure on other components, making the parallel slide gate valve more suitable for applications with large temperature fluctuations. Wedge gate valve are prone to stem or wedge jamming under high temperature conditions, but the design of the parallel slide gate valve reduces the risk of jamming or locking.

2.4 The Parallel Slide Gate Valve produced by Freeman Valve can reduce wear. The sliding motion minimizes wear on the seat surface and helps to extend service life.

2.5 The Parallel Slide Gate Valve produced by Freeman Valve is easier to maintain. Due to its simple design, the parallel slide gate valve is generally easier to disassemble and repair than other gate valve.

2.6 The Parallel Slide Gate Valve produced by Freeman Valve closes reliably in high-pressure applications. Its design prevents the risk of "wedge jamming" common in traditional gate valve and ensures safe closure even under high pressure.
