High-Quality Spring-Assist Closed Diaphragm Valve For Industrial Water Treatment

Spring-Assist Closed Diaphragm Valve for Industrial Water Treatment

Feature: A compression spring is mounted on the upper chamber of the diaphragm, and the valve seat is pushed downward by the spring tension to assist in closing the valve. Working pressure: 1-8bar Working temperature: 4-50°C

Spring assist closed diaphragm valve (SAC): A set of springs is installed in the control chamber on the diaphragm to assist closing the valve when the control pressure is insufficient. Opening the valve: When the pressure in the upper chamber of the diaphragm is relieved, inlet water pushes the valve stem open with its own pressure, easily forming a cavity for fluid flow. Closing the valve: In the event of a sudden power outage, the equipment needs to be shut down or the control pressure is insufficient, the valve seat is pushed down with the assistance of spring tension, to close the valve. Technical Advantage: 1. Streamlined flow channel, resulting in low pressure loss. 2. Control source and system fluid are independent in two chambers, making the valve control method flexible and suitable for various scenarios. 3. The valve body material is diverse, suitable for various media, and has good corrosion resistance. 4. Rubber diaphragm produced with special materials is corrosion-resistant, fatigue-resistant, and has a long service life. 5. Ingenious structural design, economical, reliable, and stable operation. 6. The standard valve is normally open. JKmatic can provide various expansion functions to meet different process requirements, such as normally closed (NC), spring-assist closed (SAC), spring-assist open (SAO), limit stop (LS), position indicator (PI), solenoid (BSO), etc., to meet diversified operational needs. Technical parameters: Working pressure: 0.15-0.8MPa Working temperature: 4-50°C Control source: Liquid/Gas Control pressure: > Working pressure Fatigue times: 100,000 times Burst pressure: ≥4 times the maximum working pressure Specifications: Four sizes: 1 inch, 2 inch, 3 inch and 4 inch.
