CS Single Disc Parallel Slab Gate Valve Class 150LB

CS Single Disc Parallel Slab Gate Valve Class 150LB, as one of the main products promoted by Wenzhou JOEPAI Valve Co., Ltd., is a gate valve using a single flat gate with parallel faces that seals by direct mechanical force against parallel seats, offering advantages in high-temperature applications by reducing jamming risk but demanding high manufacturing precision and requiring greater closing force. Widely used in fields such as petroleum, natural gas, and chemical engineering. We are committed to providing high quality, customized valve solutions to ensure the smooth progress of your project.

Product Feature:

Thermal Expansion Adaptability: In high-temperature services (e.g., steam, hot oil), the parallel structure prevents jamming caused by thermal expansion, ensuring reliable operation.

Pure Mechanical Sealing: Relies solely on forceful stem actuation for initial sealing; no pressure-assisted sealing.

Weak Low-Pressure Sealing: Prone to leakage under vacuum/low-pressure startup before system pressure builds.

High Precision Requirement: Demands ultra-precise machining of gate/seats; minor damage or deformation compromises sealing.

High Closing Torque: Requires greater operating force to compress seals (especially at low pressure) due to the absence of wedging.

Low Flow Resistance: Full-bore design minimizes pressure drop when fully open.

Metal Hard Sealing: Resists high temperatures but susceptible to wear; lapping/part replacement may be needed.

Solid Particle Tolerance: Parallel design resists clogging by impurities (superior to wedge valves).
