Product Description

Product Description

ZJHM Pneumatic Cage Control Valve

1.ZJHM Sleeve Type Diaphragm Pneumatic pressure Control Valve

 Characteristics:

         This product is composed of the pneumatic multi-springs, pneumatic actuator and the low flow resistance sleeve. This valve uses the balanced valve core, the unbalanced force is small, the permission pressure differential is big, and operation is steady. Compared with the ordinary single and double seat-regulating valve, it has low noise, simple structure and convenient assembling and dismantling characteristics.

         Its valve shape is small, the body is light, the performance is good, and the capacity is big. So it's the new type general regulating valve product. It is suitable for the common fluid medium and techniques condition industrial control system.

Performance advantages

Modular design concept, combining the American and Japanese schools of high-precision control and the German school of modular concept.

The cage valve inner cavity of the valve body is S-shaped distribution, smooth and without dead ends; there are guide wings inside the valve body, which can reduce the mutual force of the medium inside the valve body and reduce the occurrence of cavitation.

The use of sleeve guidance, large guide diameter, smooth guidance, with good dynamic stability.

The cage valve seat adopts floating design, while the sealing surface adopts tapered form to ensure good alignment of the sealing sub.

Sleeve window control flow characteristics, flow characteristics control accurately.

The structure of the inner part is balanced, allowing a large differential pressure, small operating force and large flow capacity.

Equipercent, linear and quick-open flow characteristics are available.

Good use in the temperature range of -80 to 593℃.

And pipeline connection with RF, RJ, FM and other flange type and SW, BW welding type.      

The flange distance conforms to GB/T 17213.3-2005 / IEC 60534-3-1:2000; or ISA S75.03-1992 standard.

Cage Valve Part
1. Valve Trims

According to the needs of the working conditions, different materials and surface hardening treatment can easily be chosen to meet the requirements of each function module of trim to improve its performance of the corrosion, cavitation and erosion resistant, lengthen service life.

2. Valve body

The body of LN8 series control valves consists of two passages from upper and lower, forming a shape like letter "S". The design of an elliptical section reduces the flow resistance and turbulent flow to keep the flow fluent. The flap in the middle of upper passage can reduce the eddy flow and increase the flow capacity.

3. Actuator

The standard mate of LN8 series is AM8 Multi-spring pneumatic diaphragm actuator, which can be used in many conditions with the features of strong output force, high reliability, long lifespan and extensive application. The output force changes with the number of springs. The high stress resistant diaphragm, bearing maximum pressure of 0.5 MPa air supply, gives control valve a reliable shutoff. This type of actuator has a long life cycle with more than 1 million times.
