Description
The ASCO 8221G1 solenoid valve is designed for use in HVAC systems. Since it is a normally closed valve, it remains closed unless an electrical signal is applied to cause it to open. The valve’s opening diameter is indicated by the 3/8 inch, and its pressure rating, which is good for pressures up to 150 psi, is indicated by the 5/150.This valve’s ability to close slowly is one of its primary characteristics. The valve gradually closes to eliminate water hammer, a rapid spike in pressure that may damage equipment and pipes, after the electrical signal stops. This is especially crucial for hot water systems since abrupt pressure changes can deteriorate them. Controlling the compressed air flow in pneumatic control mechanisms.
