◆ Air Actuated Diaphragm Low Temperature Control Valve Overview

The pneumatic diaphragm low-temperature regulating valve core features an upper guidance structure, with a compact valve body and an S-shaped fluid passage. It offers minimal pressure drop loss, high flow rates, a wide adjustable range, and high accuracy in flow characteristics, complying with the IEC 534-2-1976 standard.Leakage meets ANSI B16.104 standard.

Pneumatic diaphragm low-temperature regulating valves are paired with multi-spring diaphragm or cylinder actuators, featuring a compact structure and high output force.
The pneumatic diaphragm low-temperature regulating valve is suitable for low-temperature and low-pressure differential applications that require high reliability and excellent shut-off performance.
The product complies with GB/T4213-2008 standard.
