Introduction
The pneumatic sleeve regulating valve-ZJHM  is composed of a pneumatic multi spring thin film actuator and a low flow resistance sleeve valve. It uses compressed air as the power source, a cylinder as the actuator, and accessories such as electrical valves, converters, solenoid valves, and holding valves to drive the valve, achieving on/off or proportional adjustment, and thereby adjusting parameters such as pressure, temperature, flow rate, and liquid level in industrial systems.
ZJHM pneumatic sleeve regulating valve is a pressure balanced regulating valve, which adopts sleeve guidance, pressure balanced double sealing surface valve core mechanism, and is equipped with a multi spring pneumatic actuator. The flow channel is S-shaped and has the characteristics of overall work balance, large allowable pressure difference, precise flow characteristics, and low noise. Especially suitable for situations with high flow rates, large pressure differences before and after valves, and no leakage requirements. This series of products comes in various forms such as room temperature type, high temperature type, low temperature type, adjustable cutting type, corrugated pipe sealing type, etc. The nominal pressure rating of the product includes PN1.6, 4.0, 6.4, and 10.0; The valve body diameter range is DN20-300, suitable for various grades within the fluid temperature range of -196-+560 ℃. There are leakage levels of IV, V, and VI. The flow characteristics include straight lines and equal percentage characteristics.
Characteristics of ZJHM pneumatic sleeve regulating valve:
1. Adopting a balanced core, with small unbalanced force, allowing for large pressure difference, and good stability.
2. The large guiding surface of the valve core can improve the oscillation caused by eddy currents and impacts, and reduce damage.
3. Simple structure, strong interchangeability of sleeves, easy disassembly and assembly, and convenient maintenance.
4. The valve body is designed according to the principles of fluid mechanics as an equal cross-section low flow resistance channel, with a large adjustable range, inherent adjustability ratio, and increased rated flow coefficient.
5. The actuator adopts a multi spring structure with reduced height. Weight reduction.
6. The ZJHMV bellows sealed regulating valve forms a seal for the moving valve stem.
7. The ZJHMJ type regulating valve is equipped with an insulation jacket, which is used in situations where the fluid is prone to crystallization and solidification after cooling, causing blockage
