Fire Protection Special Soft Seal Gate Valve

Excellent sealing: Rubber or PTFE seals ensure zero leakage.

Quick operation: Designed for fast opening/closing in emergencies.

Corrosion resistance: Materials like ductile iron or stainless steel suit humid environments.

Low flow resistance: Full-bore design ensures high flow rates for firefighting.

High reliability: Robust construction withstands high pressure and impact.

Compliance: Meets fire safety standards (GB, NFPA, UL).

Easy maintenance: Simple structure allows quick disassembly and seal replacement.

Versatility: Suitable for water, foam mixtures, and various fire systems.

Cost-effective: Energy-efficient and low maintenance costs.

Ideal for firefighting water supply, sprinklers, and hydrant systems.

Diameter range: DN50-DN600 (or larger).

Pressure level: PN10-PN25 (or higher).

Applicable temperature: -10°C to 120°C (varies depending on the sealing material).

Medium type: fire fighting media such as water and foam mixture.

Connection method: flange connection, in accordance with international standards (such as GB, ANSI, DIN).

Valve body: the main pressure-bearing component, usually cast iron or stainless steel.

Gate: the key component for controlling water flow, which is opened and closed by lifting and lowering motion.

Sealing ring: soft sealing material, ensuring the sealing of the valve when it is closed.

Valve stem: connects the operating device and the gate to transmit the operating force.

Operating device: manual, electric or pneumatic, used to control the opening and closing of the valve.

Fire water supply system: controls the water flow in fire pipes.

Sprinkler system: an automatic water sprinkler fire extinguishing system used in buildings.

Fire pump room: installed in the pump room, controls the start and stop and flow of the water pump.

Fire-fighting soft-sealed gate valves are important components in fire-fighting systems. They have good sealing, corrosion resistance and high-pressure performance, ensuring reliable operation of the system during fires. Correct selection, installation and maintenance are the key to ensuring their long-term effective operation.
