Integrated flame arrester for absolute fire retardant and explosion-proof security.
Engineered pipe-away architecture for strictly controlled, zero-exposure emissions.
Advanced Polytetrafluoroethylene (PTFE) seating ensuring anti-frost reliability in extreme climates.
The Pressure Vacuum Relief Breather Valve with Pipe Away presents a robust, meticulously cast metallic exterior, offering a visually impenetrable barrier against harsh industrial elements. When inspecting the interior architecture, the smooth, precisely machined Polytetrafluoroethylene (PTFE) seating components reflect a commitment to frictionless, frost-resistant operation. In active petrochemical storage environments, you will not hear the typical, concerning hiss of escaping volatile organic compounds; instead, this valve operates with a silent, calculated efficiency. It allows full volumetric flow without inducing overpressure, maintaining an absolute, delicate equilibrium within your storage vessels.
By utilizing advanced principles of vapor heat transfer, the internal respiratory mechanisms remain thermally stable, completely resisting the icy crystalline buildup that typically paralyzes standard valves in sub-zero climates. The tactile solidity of its flanged connections ensures a seamless, airtight integration into your existing pipeline infrastructure. Rather than venting pungent, hazardous vapors directly into the breathable atmosphere, the engineered pipe-away configuration captures and safely routes these emissions to designated recovery systems. This eliminates noxious odors from the facility floor, protects on-site personnel, and prevents the costly atmospheric loss of highly valuable liquid assets.

Our engineering team has developed a respiratory valve that not only reacts to minute pressure differentials but proactively protects your entire storage ecosystem. The integration of advanced safety protocols ensures that your facility remains shielded from catastrophic events while minimizing product loss.
Electrostatic Neutralization: Equipped with a dedicated electrostatic protection device, ensuring the valve and the storage tank maintain the exact same potential moment, eliminating the risk of static-induced ignition.
Simplified Structural Integrity: Designed with a streamlined internal geometry that maximizes ventilation volume while drastically minimizing potential leak points.
Zero-Overpressure Full Flow: Engineered to let the seat leakage closer to the set point, allowing massive volumes of air or vapor to pass through smoothly without stressing the tank's structural limits.
Thermal Insulation Properties: The inherent insulation characteristics of the selected materials prevent rapid temperature fluctuations from compromising the internal mechanical movements.
In the highly regulated petrochemical sector, fugitive emissions are both an environmental hazard and a direct financial drain. This valve is engineered to bring seat leakage incredibly close to the exact set point.
Drastically reduces the evaporative loss of medium volatile products.
Ensures strict compliance with global environmental emission standards.
Translates directly into energy-saving benefits by retaining valuable vaporized assets within the system.
Handling combustible materials like gasoline, kerosene, and aromatics requires zero margin for error. The integration of a high-performance flame arrester transforms this breather valve into a formidable defensive barrier.
Physically blocks external flames from traveling back into the vapor space of the storage tank.
The electrostatic protection device prevents the accumulation of static charges during rapid vapor flow.
Provides certified fire retardant and explosion-proof functionality for high-risk chemical storage.
Standard breather valves vent directly into the surrounding air, which is unacceptable when dealing with toxic or highly flammable sulfur and aromatic compounds. The pipe-away configuration solves this critical issue.
By featuring a dedicated flanged outlet, it captures all escaping vapors and channels them securely into a closed-loop recovery or destruction system (such as a scrubber or flare). This structural upgrade eliminates toxic exposure for on-site workers and prevents the formation of explosive vapor clouds in the immediate vicinity of the tank farm.
Extreme cold can freeze the internal pallets of standard valves, leading to catastrophic tank implosions or ruptures. We have engineered this valve to thrive in environments plummeting to -40 °C.
Utilizes the principles of vapor heat transfer to keep respiratory moving parts warm and active.
The PTFE (Polytetrafluoroethylene) internal components naturally repel moisture, preventing ice adhesion.
Guarantees uninterrupted, anti-frost operation throughout severe winter conditions.
A storage tank is constantly breathing—expanding during the heat of the day and contracting at night, or during rapid filling and emptying processes. Inadequate venting leads to structural fatigue.
This valve guarantees full flow without overpressure. As soon as the internal pressure reaches Standard B operating limits, the valve opens fully to allow rapid equalization. It prevents the tank from ballooning under excess pressure or collapsing inward under vacuum conditions, extending the lifespan of your heavy capital equipment.
No two chemical applications are identical, which is why we offer an extensive portfolio of shell materials including HT, AL, A3, 18-8, 304, 304L, 316, and 316L.
Cast iron (HT) and Aluminum (AL) options provide cost-effective durability for standard petrochemicals.
Premium 316L stainless steel offers ultimate corrosion resistance against aggressive sulfur compounds and harsh atmospheric conditions.
The internal PTFE components remain chemically inert, preventing degradation and ensuring long-term operational integrity.
Upgrading facility infrastructure should not require extensive pipeline modifications. We manufacture this valve to seamlessly integrate into your current setup.

A standard breather valve vents excess pressure directly into the surrounding atmosphere, which can create hazardous, breathable vapor clouds if the stored medium is toxic or highly flammable. The pipe-away design features a flanged outlet that captures these emissions and securely channels them through a closed piping network to a vapor recovery unit or flare system, completely isolating the hazardous gases from the facility floor and personnel.
Yes, it is explicitly engineered for severe climates, functioning flawlessly in ambient temperatures as low as -40 °C. It achieves this through a dual-defense mechanism: the internal components are crafted from PTFE, which inherently resists moisture and frost adhesion, while the structural design utilizes vapor heat transfer principles from the stored medium to keep the respiratory valve parts warm and moving freely.
To combat aggressive media such as sulfur, aromatics, and harsh marine environments, we offer the exterior shell in high-grade stainless steel variants, including 304, 304L, 316, and 316L. Combined with the chemically inert PTFE internal seating, these materials provide exceptional resistance to chemical degradation, ensuring a long operational lifespan without rust or structural weakening.
When volatile liquids and vapors move rapidly through a system, they can generate static electricity, which poses a severe ignition risk. The built-in electrostatic protection device grounds the respiratory valve to the storage tank, ensuring both components maintain the exact same electrical potential moment. This continuously neutralizes any static buildup, preventing sparks in the highly flammable vapor path.
Absolutely. While our standard production utilizes the HG20592-97 PN1.0 flange standard, our manufacturing facility is fully equipped to produce connections according to any user-specified criteria. Whether your existing infrastructure requires ANSI, DIN, JIS, or specialized bespoke dimensions, we can machine the flanges to ensure a seamless, leak-proof installation without requiring you to modify your existing pipework.
