Manufacturing Process

Precision Casting Process: The valve body is made by casting process. The precise geometric dimensions ensure that the internal part of the valve body does not need any finishing to ensure the sealing performance of the valve. This improves the production efficiency and product quality and reduces the production cost.

Functional Advantages

Flexible Operation: It has the characteristics of simple structure and flexible operation. When operating manually, the valve can be easily opened and closed by turning the handwheel, which is labor - saving and convenient. Some valves can also be equipped with electric, pneumatic and other driving devices to achieve automatic control to meet the needs of different working conditions.

Reliable Sealing: Through the integrally coated gate, special sealing structure and precise manufacturing process, good sealing performance is achieved, which can effectively prevent medium leakage and ensure the normal operation of the system.

Wide Application Range: It is widely used in pipeline projects such as water supply and drainage, fire protection, air - conditioning, gas, petroleum, chemical industry, water treatment, municipal administration and shipbuilding to control the fluid. It can adapt to different media and working conditions.

A Fire Gate Valve Working in Fire Piping Systems

1.Installation:

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.

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.
