Electric Single Seat Control Valve
Product Overview
The ZDLP electric single-seat regulating valve adopts a top-guided structure, a compact valve body, an S-shaped fluid channel, small pressure drop loss, large flow volume, wide adjustable range, and high flow characteristic accuracy. The guide area of the valve core guide part is large, and it has the characteristics of strong seismic resistance. The valve seat closing performance meets the GB/T4213-92 standard. The regulating valve is equipped with a small, sturdy, and high-precision actuator that receives ON-OFF or 4-20mADC or 1~5V DC signals for proportional action. It is more suitable for use in high temperature, low temperature and high pressure occasions that require high reliability and closing performance. The unique cage design can also be used in harsh working conditions such as scouring and cavitation. The valve seat can be used on both sides to increase the service life. It can be quickly installed and disassembled without special tools, and it is cost-effective.

Pneumatic Control Valve
Product Overview
The ZJHP type pneumatic diaphragm single-seat regulating valve adopts a top guide structure, a compact valve body structure, an S-shaped fluid channel, a small pressure drop loss, a large flow rate, a wide adjustable range, and a high flow characteristic accuracy.
The guide area of the valve core guide part is large, and it has the characteristics of strong vibration resistance. The valve seat closing performance meets the GBT4213-92 standard. The regulating valve is equipped with a multi-spring diaphragm actuator, which has a small structure and a large output force. It is more suitable for use in high temperature, low temperature and small pressure difference before and after the valve that require high reliability and closing performance. The unique cage design can also be used in harsh working conditions such as scouring and cavitation. The valve seat can be used on both sides to increase the service life and can be quickly installed and disassembled without special tools. High cost performance.Extra Features- Premium Quality

Piston Pressure Reducing Valve
Structural features and uses:
This series of pressure reducing valves are pilot piston pressure reducing valves. They are composed of two parts: the main valve and the pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, cylinder sleeve, spring and other parts. The pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, regulating spring and other parts. The outlet pressure is set by adjusting the regulating spring pressure, the outlet pressure change is sensed by the diaphragm, and the size of the flow area of the main valve throttling part is adjusted by the pilot valve opening and closing to drive the piston to achieve the pressure reducing and stabilizing function.
This product is mainly used in steam pipelines to play a role in pressure reducing and stabilizing.Extra Features- Premium Quality
