Application advantage
The application range of SUN valves is very wide, not only covering
traditional industrial machinery and equipment, but also in
emerging fields such as solar energy and environmental protection
equipment. Especially for applications in high temperature
environments, SUN valves demonstrate excellent temperature
resistance and stability . Technological progress and product innovation: with the
increasingly severe problems of energy conservation and emission
reduction, green environmental protection and the emergence of
emerging technologies such as artificial intelligence, the valve
industry is undergoing an overall transformation to explore the
direction of intelligence, low carbonization and customization.
Technical specification
This valve is a pilot to open check valve. It has a sealed pilot, a steel seat, and is vented. It allows free flow from the valve (port 2) to the load (port 1) and blocks flow in the opposite direction. Pressure at the pilot (port 3) will open the valve from port 1 to port 2. Pilot pressure needed to open the valve is directly proportional to the load pressure at port 1. The valve is insensitive to pressure at port 2 because the spring chamber is referenced to the vent .
Instructions for use
Pilot pressure as low as 75 psi (5 bar) higher than the pressure at the vent can prevent the valve from closing.Will accept pressure at port 4 (vent) but can not exceed 5000 psi (350 bar).Pilot-to-open check cartridges are locking valves, not motion control valves. For motion control applications, use counterbalance valves.Four-port pilot-to-open check cartridges and four-port counterbalance cartridges are physically interchangeable (i.e. same cavities, same flow path for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
