Product Description

Ensure reliable firefighting agent delivery with our UL/FM-approved 20mm metered valve, the critical proportioning component in aqueous film-forming foam (AFFF), AR-AFFF, and Class B fire suppression systems.

Engineered for extreme reliability, this heavy-duty flow control valve precisely meters foam concentrate into water streams at predetermined ratios (1%, 3%, 6%) under high-pressure conditions. Constructed from corrosion-resistant bronze or ductile iron with stainless steel internals, it withstands hydraulic shock, vibration, and corrosive concentrates.

The robust metering mechanism features a calibrated orifice and hardened trim, maintaining accuracy (±5% of set point) even with fluctuating inlet pressures. Its twenty-millimeter port size integrates seamlessly with standard fire system piping (NPT threaded).

Key features include tamper-proof adjustment, visual ratio indicator, minimal pressure drop, and compliance with NFPA 11, 16, and 2001 standards. Essential for foam skids, fire trucks, industrial storage tank protection, hangar deluge systems, and any facility requiring certified, dependable foam proportioning.

Key Features

Certified Fire System Valve: UL Listed and FM Approved for use in critical fire suppression applications.
Accurate Proportioning Component: Precisely meters foam concentrate at specified ratios (1/3/6%) under operational pressures.
Robust Flow Control: Heavy-duty construction ensures reliability in high-pressure and emergency scenarios.
Fail-Safe Operation: Tamper-resistant design maintains set proportioning ratio even under system pressure surges.
Standard Twenty-Millimeter Connections: Compatible with NFPA-standard fire protection piping and fittings.

Application Scenario

Precisely injecting 3% AFFF concentrate into the water main feeding an aircraft hangar's deluge sprinkler system during a fire event, ensuring optimal foam blanket formation.

Frequently Asked Questions

Q: Is this 20mm metered valve compatible with alcohol-resistant (AR) foam concentrates?

A: Yes, models with compatible seals (typically Viton) are specifically designed for use with AR-AFFF and other polar solvent foams.

Q: What is the maximum working pressure for the fire suppression valve?

A: Standard models are rated for 250 PSI (17.2 bar) working pressure. Higher pressure ratings (e.g., 350 PSI) are available.

Q: How often does the proportioning component require recalibration?

A: NFPA 25 recommends annual inspection and flow testing. Recalibration is typically needed every 5 years or after any significant system disturbance.

Q: Can the valve be installed vertically or horizontally?

A: Yes, the metered valve is designed for installation in any orientation without affecting its proportioning accuracy.

Q: Are service kits available for the twenty-millimeter valve internals?

A: Yes, authorized service kits containing seals, springs, and wear parts are available to maintain system compliance and performance.
