What are the features and benefits of Parallel Slide Gate Valve?

The features and benefits of a Parallel Slide Gate Valve include:

1. Enhanced Seat Integrity: The design of the Parallel Slide Gate Valve relies on the primary system pressure acting on the downstream disc for seat integrity. This eliminates the need for wedging action or additional loading on the seats, ensuring a secure seal and minimizing the risk of leaks.

2. Safety in High-Temperature Service: The inherent design of the Parallel Slide Gate Valve makes it resistant to thermal binding concerns. This provides a distinct safety advantage in high-temperature applications where other valve types may experience issues due to thermal expansion and binding.

3. Superior Strength and Durability: Parallel Slide Gate Valves are constructed with superior strength forgings or high-quality castings for the valve body. This ensures robustness and durability, allowing the valve to withstand demanding operating conditions and prolonged service life.

4. Precision Guided Operation: The unique parallel slide forged cage unit design incorporates all operating parts of the slide discs and is precision guided. This precise guidance enhances the performance and reliability of the valve, resulting in longer disc, seat, and body life.

5. Erosion Resistance: The seating faces of Parallel Slide Gate Valves are hardfaced, meaning they are coated with a hard material. This hardfacing helps to resist erosion caused by the flow of fluids, improving the valve’s longevity and maintaining its sealing capabilities.

6. Reduced Operating Torque: Parallel Slide Gate Valves feature a non-rotating stem, which requires lower operating torque compared to other valve designs. This reduces the effort and energy required to open or close the valve, enhancing operational efficiency.

7. Pressure Equalization and Prevention of Issues: To ensure the valve operates effectively under various conditions, bypass valves are recommended to equalize pressure across the disc before opening. Nantong TH-Valve offers equalizing and bypass pipes and valves in different configurations, preventing over pressurization, pressure locking, and thermal binding.

8. Extended Service Life and Emission Control: Optional live-loading of packing is available for Parallel Slide Gate Valves. This feature helps to extend the service life of the valve, particularly in applications with large pressure/temperature transients or frequent cycling. It also assists in reducing emissions, contributing to environmental compliance.

Overall, the features and benefits of Parallel Slide Gate Valves make them suitable for clean service, steam, and high-temperature applications, offering reliability, safety, and longevity in valve operation.
