untold damages to a property can be done by a sudden fire event, but sometimes efforts to put out the fire can be very catastrophic. the base of a fire protection system is made by high-quality, high-performance firefighting valves which deliver water safely and efficiently when you require it the most. the contamination and flooding from water sources that are used in the fire protection system are prevented by pressure-activated check valves. a combination of gravity tanks, fire department connection, and municipal water supplies are used by most of the fire sprinkler systems for providing water to sprinkler heads. this wanted reverse flow of water is prevented by check valves. many check valves come with a hinged clapper with a spring that keeps the valve closed until the water flowing from some water source opens it. low-cost and lightweight control over water flow in fire sprinkler and standpipe systems are provided by butterfly valves.
the flow of water is stopped via a butterfly valve by rotating an internal disc. the movement of water into piping stops when the disc is rotated 90 degrees. butterfly valves work just like a control valve capable of shutting off the flow of water to whole sections of fire sprinkler or standpipe systems. gate valves are bi-directional isolating valves that open up by lifting a rectangular or round gate out of the path of water flow. gate valves are designed to be the control valves in many of fire protection systems gate valves need to be used only in fully opened or fully closed positions. they are operated manually by multi-turn valves and are operated by a hand wheel in a counter-clockwise direction and is closed in a clockwise direction. built on years of experience, our supplied firefighting valves are incredibly versatile, offering you more ways to take control of a fire on the ground.

indicating valves physically show whether a valve is open or closed. a closed valve indicates that no water will flow beyond the valve and serves to alert the a butterfly valve isolates or regulates the flow of fluid through piping systems. while they can be used with liquids, gases, and even semi- dpv-1-web. model dpv-1: dry system. a dry pipe sprinkler system is recommended for use in environments exposed to freezing temperatures. benefits: simple,, fire sprinkler control valve location, fire valves, fire fighting gate valve, fire sprinkler control valve assembly, fire suppression systems, residential fire sprinkler control valve, fire suppression system examples, alarm check valve, automatic drain valve for fire sprinkler system, indicating valve fire protection. there are four main types of check valve for fire protection:alarm check valve.swing check valve.grooved check valve.grooved shotgun riser check valve.
