Reliable dry system valves are designed to protect areas subject to temperatures below 40°F (4°C). Dry sprinkler systems have compressed nitrogen or air in the system piping, with water under pressure held below the clapper of the valve.

Aug 22, 2018 · Hopefully with today's post if you've been in that same boat there's enough to better understand the basic components of a dry pipe valve. 1. The valve is in the closed position (clapper inside the valve is horizontal) and air pressure keeps the clapper closed. 2. A sprinkler activates, releasing air pressure at the sprinkler. 3.

Tyco® Model DPV-1 Dry Pipe Valves are differential valves that automatically control the flow of water into dry pipe fire protection sprinkler systems. These valves also provide for actuation of …

For use where piping may freeze such as unheated warehouses, outdoor parking garages or stadiums. Actuation options: Series 776 Low-Pressure Actuator. Available bare, pretrimmed, as a Vic-Quick riser or in a Series 745 FireLock Fire-Pac cabinet.

Tyco® dry system valves are ideal for spaces that are exposed to freezing temperatures — like unheated warehouses, garages, and loading docks. Our DPV-1 dry system valves feature an easy external reset for quick setup and maintenance.

The Central Dry Pipe Valve is a dry pipe sprinkler system water-supply control valve that makes possible the installation of sprinkler systems in buildings subject to freezing temperatures.

A dry valve is a fire protection device that stops the flow of water into the system’s pipes until a fire triggers sprinkler activation. The dry valve operation is housed in a heated location and uses pressurized air or nitrogen to fill the pipes.

Fire sprinkler systems utilizing dry pipe valves, pre-action valves, and dry pilot-actuated deluge valves play crucial roles in safeguarding various facilities against fire hazards, particularly in environments where traditional wet pipe systems are impractical.

The TYCO Model DPV-1 Dry Pipe Valve is a differential valve for automatically controlling the flow of water into dry pipe fire protection sprinkler systems upon operation of one or more auto-matic sprinklers. The DPV-1 valve also provides for actuation of fire alarms upon system operation.

Sep 18, 2023 · A dry sprinkler system is a type of fire protection system that utilizes air instead of water in its pipes, avoiding the risk of frozen and burst pipes in environments where water could freeze. The system is made up of several different components, including the dry pipe valve, a control valve, and a quick-opening device.
