1. Product Overview
Safety valves are critical devices designed to protect pipeline systems, ensuring pressure and stress stability during operation. If the system pressure exceeds the allowable limit, the safety valve automatically discharges the fluid to help control and stabilize the media within the system.
2. Technical Specifications
Customers generally focus on the following sustainable and compliant technical specifications:
| Feature | Technical Specification |

| Pressure Test Standards | API 527, GB/T 12241 – 2005. |
| Pressure Ratings | Class 150, 300, 600, 1500 lbs; PN10 ~ PN160; or JIS 10K ~ JIS 40K. |
| Face-to-Face Dimensions | API 526. |
| Flange Dimensions | ASME B16.5, ASME B16.47, etc. |
| Valve Sizes (Nominal Diameter) | ½” ~ 24” or DN15 ~ DN600. |
| Body Materials | Ductile Iron (DI), Cast Iron (CI), Bronze, WCB, A105, CF8 (304), CF8M (316), CF3 (304L), CF3M (316L), etc. |

3. Working Principle and Outstanding Features
To effectively convince your customers, you should emphasize these high-value engineering features:
- Simple and Reliable Principle: The valve operates automatically based on downstream system pressure. Under normal pressure, the valve remains closed, allowing the fluid to pass through.
- Instant Overpressure Protection: In the event of a critical pipeline malfunction leading to sudden pressure spikes, the valve immediately opens to vent excess fluid, stabilizing the pressure.
- Premium Brand Reputation: Supplied by VINAPECO, these safety valves consistently meet high-quality standards. They are highly trusted by customers for their exceptional durability and high resistance.
- Cost-Effective Investment: Offers long-term reliability and heavy-duty performance at a highly competitive price point, making it the ideal choice for consumers.
4. Why Should Customers Choose This Valve?
💡 Expert Advice for Customers
If your pipeline system runs under high-pressure conditions or manages hazardous fluids like gas, fuel, or fire-extinguishing media, installing a certified safety valve is non-negotiable. It minimizes the risk of catastrophic pipe bursts and equipment failure, saving long-term maintenance costs.
🌟 Key Advantages
- High Durability: Constructed from premium materials (WCB, A105, SS316) that withstand high pressures and minimize body deformation.
- Excellent Market Versatility: With sizes ranging from DN15 to DN600 and multiple standards (ANSI, JIS, DIN), it easily integrates into any existing global piping system.
- Proven Performance: Trusted across high-risk industries including petrochemicals, LPG logistics, and commercial firefighting networks.
5. Common Applications
- Liquefied Gas Systems: Installed on storage tanks and distribution lines to prevent gas overpressure.
- Petroleum & Oil Gas: Protects refinery pipelines, pumping stations, and fuel transport systems.
- Firefighting (PCCC): Controls pressure surges in high-pressure water deluge and sprinkler pump networks.
