Non-Rising Stem Resilient Seated Gate Valve for Fire Fighting

The Non-Rising Stem Resilient Seated Gate Valve for fire fighting provides an efficient flow control solution specifically designed for fire protection systems where vertical space is limited. These non-rising stem gate valves feature a compact design that maintains consistent external dimensions while delivering reliable performance in demanding fire safety applications. The resilient seated gate valves incorporate an advanced elastomeric seal that ensures bubble-tight closure and superior sealing capabilities, even after extended periods of inactivity. Engineered with durable cast iron construction and corrosion-resistant epoxy coating, the fire fighting gate valves withstand harsh environmental conditions while maintaining operational readiness. The flanged connection design of the non-rising stem valves facilitates straightforward installation and ensures secure integration with fire protection piping networks.

The Resilient Seated Gate Valve Features and Benefits:

Non rising stem, save installation space.

3 O-rings sealing, zero leakage, safety and reliable.

Selfilubricating bushing design,prevent rust and damage O-rings to cause leakage,easy to make on-line maintenance,even under pressure.

A Fire Gate Valve Working in Fire Piping Systems

1.Installation:

Grooved connections:

Prepare the pipes by ensuring they have grooved ends compatible with the valve's grooved connections

Connect the valve to the pipes using grooved couplings. Follow the manufacturer's guidelines for proper installation procedures.

Flanged connections:

2.Flow Control:

The valve can be positioned to either allow or block the flow of water in the fire piping system. In emergencies, the valve can be quickly closed to control the flow and direct water to specific areas.

3.Regular Inspection:

Periodically inspect the valve to ensure it is in good working condition. Check for any signs of wear, damage, or leakage.

4.Testing:

Conduct regular tests on the entire fire protection system, including the valve, to ensure proper functionality. This may include pressure tests and flow tests.

5.Emergency Response:

In the event of a fire, the valve can be part of an automated or manual system to control the flow of water to the affected area.Always follow the manufacturer's guidelines and adhere to local fire protection codes when installing and maintaining gate valves in fire piping systems. Regular inspections and testing are crucial to ensure the reliability of the system during emergencies. If you're not familiar with fire protection system installations, it's advisable to consult with a professional or someone experienced in this field for guidance.
