Products Details

ZJHL type top guided porous cage control valve is an efficient industrial control valve, it has a variety of characteristics and advantages, suitable for a variety of strict process environment. The following is a detailed description of the ZJHL type regulating valve:

Features: ZJHL series pneumatic cage type single seat regulating valve is a top guide to the single seat regulating valve, with symmetrical porous cage valve disc design, this design can be more effective control of noise and cavitation, suitable for a variety of harsh working conditions. In addition, it can also customize different flow coefficients according to the customer's process requirements, and can choose multi-spring pneumatic film mechanism or electric actuator.

Material and structure: the material of the valve body and valve cover is usually ZG230~450, ZG1Cr18Ni9Ti, etc. The material of the valve core and valve seat can be 1Cr18Ni9Ti or 1Cr18Ni9Ti plus PTFE or Strilai alloy surfacing. In addition, components such as balance seals, packings, bellows, film caps, corrugated diaphragms, springs and stems are made from corresponding high-performance materials.

Performance parameters: The ZJHL pneumatic film cage regulator is designed to reduce the noise of compressible fluids, with a streamlined flow path and a pressure balanced spool structure, providing excellent dynamic stability and low noise characteristics. It is suitable for controlling high-pressure differential fluids at various temperatures.

Technical parameters: The nominal diameter of the regulating valve ranges from DN20 to DN300, with different seat diameters and rated flow coefficients to adapt to different flow requirements. It is also available in a variety of nominal pressure grades and bonnet forms to suit different operating conditions.

Actuator technical parameters: ZJHL pneumatic film cage regulator can be equipped with multiple models of multi-spring film actuators, with different effective area, stroke length, spring range and diaphragm material to meet different control needs.

Product selection: In the selection, it is necessary to consider the nominal diameter of the valve body, working pressure, process media, application occasions and valve body materials and other parameters, as well as the form of the actuator, control mode and mode of action.

After-sales service: The products provided usually have a 7-day delivery period and a 12-month warranty period, and also include free training services on the installation and commissioning site.

Leakage and performance indicators: the leakage of the metal seat is less than 0.01% of the rated capacity of the valve, and the leakage of the soft seat is less than 10^-7 of the rated capacity of the valve, meeting the ANSI B16.104-1976 Class IV standard. Performance indicators such as basic error, return error and dead zone also have clear parameters.

ZJHL control valve is widely used in industrial automation and process control because of its high performance and reliability.
