HDFIRE – Priming Shut-Off Valve for Deluge Valve

Hdfire Priming Shut-Off Valve Model PSV1 HD Priming Shut-off Valve model PSV1 is a small diaphragm operated valve. It is used to positively shut off the priming water supply to a deluge valve upon deluge valve operation. The Priming Shut-Off Valve for Deluge Valve is a critical component in deluge fire protection systems, specifically designed to prevent water from flowing into the deluge valve during system priming or maintenance procedures. This valve ensures that the deluge valve remains dry and inactive until it is needed to respond to a fire emergency. During system priming or maintenance, it is essential to isolate the deluge valve from the water supply to prevent inadvertent activation and potential flooding. The Priming Shut-Off Valve serves this purpose by providing a means to manually close off the water supply line to the deluge valve temporarily. When the deluge system is in operation, the Priming Shut-Off Valve remains closed, preventing water from entering the deluge valve. However, in the event of a fire, the valve can be opened remotely or automatically to allow water flow into the deluge valve, initiating the fire suppression process. These valves are typically constructed from durable materials such as stainless steel or brass to withstand the rigors of continuous operation and harsh environmental conditions. They may also feature manual or remote actuation options for convenience and flexibility.
