How does an Inbal valve work?
The Inbal Automatic Control Valve is a pressure operated, sleeve actuated valve designed from basic concepts, with a built in actuator to function as a control valve in fire protection. The Inbal Valve utilizes the unique N.M.M.P. The Inbal Valve withstands pressure surges and is entirely resistant to false tripping.
What is the pressure rating for Inbal make deluge valves?
300 psi
The standard material Inbal Deluge Valve is rated to 300 psi (21 bar) and is available in sizes 1½” (40 mm) to 12″ (300 mm).
What is the function of deluge valve?
A deluge fire protection system has unpressurized dry piping and open sprinkler heads. The system is directly connected to a water supply and when the system is activated, a deluge valve will release the water to all the open sprinkler heads. The valve is opened when activated by a heat or smoke detection system.
What is trim in deluge valve?
The basic trim or type is required on deluge valve regardless of the release system. It contain those components which are required in all types of installation, such as the main drain valve, priming connection, drip check valve, emergency release valve and pressure gauges.
How many types of deluge valves are there?
Deluge valve is available with several trims including wet pilot, dry pilot, electric release, manual release, etc.
How do I activate deluge?
How is a Deluge System activated? The sprinkler heads on a Deluge system are fused together and operate as one when activated. The valve is opened when activated by heat or smoke detection systems. Once activated, the water is released into the piping and out of the sprinkler heads.
What are the types of deluge valve?
Types of Deluge Valves
- a) Basic Valve. The basic trim or type is required on deluge valve regardless of the release system.
- b) DRY PILOT TRIM (PNEUMATIC RELEASE) TYPE.
- c) WET PILOT TRIM ( HYDRAULIC RELEASE) TYPE.
- d) ELECTRIC RELEASE TRIM TYPE.
- e) TEST AND ALARM TRIM WITH SPRINKLER ALARM TYPE.
What type of valve is a deluge valve?
system actuation valve
A deluge valve is a type of system actuation valve that is opened by a detection system that is installed in the same areas as the spray nozzles or by remote manual operation supplying water to all spray nozzles.
What activates a deluge sprinkler system?
What is a deluge set?
: a large monitor nozzle used in fire fighting to produce a deluge.
How do you activate a deluge valve?
What makes the Inbal deluge valve so easy to install?
The Inbal deluge Valve is compact, lightweight, and is provided with a preassembled trim – all of which minimize the installation time and make it simple and easy. The Inbal Valve opens fast, yet smoothly, preventing water hammer. The Inbal Valve design prevents false tripping and it can be reset by a thumb-activated knob.
How big is a pressure reducing deluge valve?
The pressure reducing ON/OFF deluge valve models are available in diameter sizes from 2” (DN 50) to 10” (DN 250). The pressure reducing deluge valves models are used to control the pressure of water or foam/water flow for water spray or foam fire protection systems.
How are deluge valves used in fire protection?
The pressure reducing deluge valves models are used to control the pressure of water or foam/water flow for water spray or foam fire protection systems. In normal operating conditions, the deluge valves are held closed by the control solenoid valve.
When to use an electro pneumatic deluge valve?
The Electro-Pneumatic Deluge Valves are recommended for those applications where it is preferable to keep the solenoid valve dry, such as those with sea water or foam concentrate. The Electro-Pneumatic Deluge Valves are designed for external resetting, without opening the valve.
