Reliable Over-Pressure Protection

Engineered to safeguard cryogenic and LPG storage systems, the AR4100 Series delivers uncompromised security through precise pressure relief. Its wide set pressure range, bubble-tight shutoff, and durable materials make it indispensable for operators seeking consistent, ASME-approved performance in highly regulated environments.

Angle Body Design for Superior Flow

The distinctive 90 angle configuration allows efficient flow and release of overpressure, minimizing turbulence and ensuring rapid venting. Mounting vertically upward optimizes operation, while a compact size and 1/2-inch NPT port facilitate easy integration into existing systems.

Robust, Low-Maintenance Construction

Constructed from forged brass with a stainless steel spring and optional corrosion-resistant bonnet, the AR4100 Series is built to last. Its mechanical design requires no external power, significantly reducing maintenance and operational costs while providing reliable service even in extreme temperatures.

FAQ's of REGO Angle Relief Valve, ASME AR4100 Series:

Q: How is the REGO ASME AR4100 Series Angle Relief Valve typically installed?

A: The valve is designed for vertical upward mounting, allowing for optimal pressure relief performance. Its threaded 1/2 NPT female connection ensures secure and straightforward installation on cryogenic and LP-Gas cylinders or tanks.

Q: What are the primary applications for this angle relief valve?

A: This valve is specifically engineered for use in protecting cryogenic and liquefied petroleum gas (LPG) storage cylinders and tanks, ensuring safe release of excess pressure in these systems.

Q: When should I select a valve with PTFE/Teflon seats and a stainless steel spring?

A: Select this configuration if your application involves exposure to aggressive chemicals, temperature fluctuations ranging from -320F to +165F, or requires enhanced corrosion resistance and leak prevention for high-purity or cryogenic media.

Q: Where can this valve be used in terms of geographic and industrial scope?

A: Being an ASME Section VIII, Division 1 code-approved product, the valve is suitable for use in internationally regulated environments-across industries handling liquefied gases, especially in India and regions adopting ASME codes.

Q: How does the blowdown specification benefit my system safety?

A: A blowdown not exceeding 5% of set pressure ensures that once the valve opens and relieves excess pressure, it quickly resets and achieves a bubble-tight shutoff, reducing unnecessary product loss and improving operational safety.

Q: What process is involved in setting the pressure range for this valve?

A: The set pressure can be chosen between 15 and 250 PSIG, determined by your system's requirements. The spring-loaded control system allows precise adjustment and reliable actuation per application needs.

Q: What are the main benefits of choosing this angle relief valve over conventional designs?

A: With its compact angle body, corrosion-resistant components, and bubble-tight shutoff, it offers space efficiency, extended service life, and superior performance in demanding environments, all while meeting stringent ASME safety standards.
