Weflo Pressure Relief Valve Fig. 1319
Industrial-Grade Overpressure Protection for Liquid Systems
Introduction: The Critical Role of Relief Valves in Industrial Fluid Systems
In any industrial flow network—whether in water distribution, fire protection, chemical plants, or process cooling—valves are essential for ensuring system integrity, reliability, and safety. While gate valves isolate flow, ball valves provide rapid shut-off, and check valves prevent reverse flow, pressure relief valves play a uniquely critical role: protecting equipment and pipelines from dangerous pressure surges.
Pressure surges, whether caused by pump failures, sudden valve closures, or thermal expansion, can rupture pipes, damage control valves, or even lead to catastrophic failures. The Weflo Pressure Relief Valve Fig. 1319 is engineered to automatically release excess pressure from a system before it causes harm. With a heavy-duty ductile iron body, corrosion-resistant stainless-steel internals, and a spring-loaded design that ensures immediate response, this valve is the safety net your system can’t afford to skip.
Complete Product Overview – Weflo Fig. 1319
The Weflo Pressure Relief Valve Fig. 1319 is a spring-loaded relief valve designed to maintain upstream system pressure within a safe range. When inlet pressure exceeds a factory-set or adjustable limit, the valve opens to relieve the excess pressure, then closes tightly once normal conditions are restored.
Its design offers several operational benefits—modulating performance, wide flow capability, and inline serviceability. Built to AWWA C606 standards, this valve is ideal for use in municipal, industrial, and fire protection systems.

Functional Advantages
1. Reliable Overpressure Protection
The Fig. 1319 opens immediately when inlet pressure exceeds the pre-set limit, relieving fluid to prevent damage to downstream piping, valves, and equipment. It then reseals tightly when the pressure returns to a safe level.
2. Wide Flow and Pressure Range
Whether it’s a small pressure deviation or a full-system surge, the valve handles varying flow rates with ease. Its modulating performance means it doesn’t simply “snap open,” but gradually opens in proportion to the pressure spike.
3. Stainless Steel Internals for Corrosion Resistance
Components like the seat, stem, and spring are made of stainless steel for durability in potable water, chlorinated systems, and light chemical applications. The valve resists corrosion and erosion for a longer service life.
4. Inline Serviceability
The valve can be maintained or repaired without being removed from the piping system—saving time, labor, and cost. Bonnet access allows technicians to inspect or replace springs, seals, or seats as needed.
5. Compact Design with AWWA Compliance
The valve’s short face-to-face dimension saves space in confined pump rooms or fire riser cabinets. Grooved ends comply with AWWA C606 for easy installation using couplings.
Industrial Applications
The Weflo Pressure Relief Valve Fig. 1319 is ideal for various industries where overpressure must be mitigated reliably and automatically.
Fire Protection Systems
Fire pump discharge lines often experience high-pressure surges, especially during rapid start/stop cycles. The 1319 valve protects check valves, gate valves, and riser components from overpressure.
Municipal Water Systems
In urban water distribution networks, pressure can fluctuate due to elevation changes or pump cycling. Relief valves prevent burst pipes and help stabilize pressure in low-lying areas.
HVAC and Cooling Systems
In chilled water or glycol systems, pressure surges from pump startups or zone valve closures can be damaging. Fig. 1319 maintains safe pressures to protect coils, pumps, and control valves.
Water Treatment and RO Systems
Reverse osmosis skids and dosing lines operate under varying pressures. A pressure relief valve ensures the membrane housings or dosing pumps are not over-pressurized.
Industrial Process Lines
In plants handling light chemicals, hot water, or washdown systems, pressure relief valves are essential to protect downstream instrumentation, fittings, and flexible hoses.
