Product Description

Description
Dynamically balanced electric regulating two-way valves are used to control flow in regional refrigeration systems. Electric or electric actuator is assembled to transmit the control signal of electric controlling equipment and connect the regulator. And has the communication function to transfer to the upper computer, which is conducive to the energy saving operation control of the system
Key features
Valve diameter DN15 ~ DN25, nominal pressure PN16/25, suitable for liquid temperature up to 120 °C.
The combined dynamic balanced electric regulating two-way valve comprises a valve body, a film actuator and an adjustable orifice plate (connected to the electric heating actuator), and the maximum flow rate can also be mechanical at the orifice plate


Regulating characteristic

• Low maintenance and no auxiliary energy required
• Compact design
• Single seat body with a balanced spool ensures high accuracy for maximum adjustable flow
• Control quality is independent of pipe network pressure difference, for example, temperature control equipment is used to control temperature
• Suitable for water and other liquids, so that the material is not susceptible to corrosion

Working principle
The process medium flows through the combined in the direction indicated by the PICV valve body arrow. Dynamic balance electric regulation two-way control valve. Orifice (1.2) release area and spool (3) determine the flow rate. A pressure difference p is generated when the process medium flows through the orifice. The pressure difference is transmitted through the pressure guide tube (11) and the spool hole to the working diaphragm (6.1), where it is converted into the positioning force. The thin film actuator controls the p limit at the orifice plate and the flow determined by the orifice plate to ensure that the spool spring force is balanced with the thrust of the actuator. The maximum flow rate is adjusted by the set point regulator (12) to adjust the maximum opening of the orifice plate. If the flow required by the device is lower than the adjusted maximum flow, the electric actuator will position the orifice plate accordingly. Since the pressure difference through the orifice plate (limited) should remain constant when the network pressure difference changes, the weight of the control valve (orifice plate based on electric operating pressure) is approximately 1. Therefore, the control quality of climate compensation temperature control equipment is not affected by the pressure difference through the pipe network.

Quality Control

 

Hot forge

 

Our brass valve is produced by forging, through forging the valve product strength is greater, no porosity, can effectively prevent the leakage of the valve body.

CNC Machining

Our products are processed by precision CNC machine tools, with high machining accuracy up to 0.1 micron. We have machining centers to meet customers' requirements for products with high coaxiality




 

Machining Inspection

 

In our machining process, each size needs to be strictly tested. Workers will conduct a self-inspection of their products every 2 hours, and QC will conduct a workshop inspection every 2 hours to ensure that the size of products fully meets the requirements of the drawings

Assembly Room

Our assembly shop USES the assembly line, the result of teamwork can guarantee the output of a large quantity of products.100% of the products on the production line need to pass the leak test. We use the pressure of 6-8bar to test each product. Only after passing the test can the products be packed into cartons.
