Low-noise pneumatic diaphragm control valve

The pneumatic/electric low-noise control valve adopts a modular design with strong universality and interchangeability, and has a compact structure. The specially designed symmetrical small-hole valve internals can reduce noise and achieve pressure reduction, thereby preventing flashing and cavitation. It is especially suitable for various high-pressure difference and low-noise occasions, meeting user requirements. The valve seat and valve body clamping connection method, which can be used on both sides, effectively improves the sealing level and stability of the valve, and is extremely convenient for use and maintenance, thus greatly improving the overall performance of the control valve. <br/> This series of products has various types, including standard type, heat dissipation type, low temperature type, and bellows seal type. The nominal pressure rating of the product is PN(MPa) 1.6, 2.5, 4.0, 6.3, 10.0 (150lb, 300lb, 600lb): Valve body diameter range DN(mm) 20~200 (3/4”~8”): Applicable fluid temperature -196~+560℃. Various grades are available within the range: Leakage standard has Class Ⅳ, Class Ⅴ, Class Ⅵ; Flow characteristics have linear and equal percentage. A variety of varieties and specifications are available.

Pneumatic/electric direct-acting cage single-seat regulating valve

The pneumatic/electric direct-acting cage-style single-seated regulating valve is a pressure-balanced single-seated regulating valve. It uses a cage-type sleeve guide and single-seat sealing structure, with an S-shaped streamline flow path and imported MA43 series balanced sealing rings. The overall characteristics include stable operation, large allowable pressure difference, precise flow characteristics, and low noise. Equipped with a multi-spring actuator or electric actuator, it is suitable for applications with small allowable leakage and large pressure difference across the valve. <br/> This series of products includes standard, bellows-sealed, insulated jacket, high-temperature, and low-temperature types. Nominal pressure ratings are PN (MPa) 1.6, 2.5, 4.0, 6.4, 10.0; valve body diameter range DN (mm) 40~400; applicable fluid temperature -150~+250℃; leakage standard is Class IV; flow characteristics include linear and equal percentage. A wide variety of specifications are available.
