Description
Product Overview
The Conrader 1/4″ ASME brass safety relief valve is engineered to provide precise pressure control for a wide range of compressed air applications. Constructed from high‑grade brass, the valve offers excellent corrosion resistance and long‑term durability, making it suitable for harsh industrial environments. Its pop‑off design activates at a calibrated 175 psi, safely venting excess pressure to protect compressors, tanks, and downstream pneumatic tools from damage.
Featuring a silicone rubber soft seat, the valve ensures a tight, leak‑free seal even under fluctuating pressure conditions. The inlet connection utilizes a standard 1/4‑inch NPT (National Pipe Tapered) thread, while the outlet is a matching MNPT size, allowing straightforward integration into existing air systems without the need for additional adapters. The compact dimensions (1.75 x 0.75 x 0.75 inches) and lightweight design (0.634 oz) enable easy installation in confined spaces.
Each unit is stamped with “UV” and “NB” symbols, confirming its compliance with American safety standards and its suitability for use in both commercial and residential settings. The valve’s performance is verified to stay within ±3 % of the set pressure, delivering consistent and reliable protection over the product’s lifespan.
Usage
This safety relief valve is ideal for a variety of compressed‑air scenarios, including workshop compressors, air‑tank storage systems, pneumatic tool stations, and automated manufacturing lines. It excels in environments where pressure spikes are common, such as during rapid valve opening, sudden load changes, or temperature fluctuations that can cause air expansion.
Maintenance technicians and system integrators will appreciate the valve’s straightforward installation process: simply thread the inlet onto the compressor outlet and secure the outlet to the vent line. No special tools or additional fittings are required, reducing downtime and simplifying routine inspections. The valve’s pop‑off action provides a clear visual indication of pressure release, allowing operators to quickly assess system status.
Because the valve is manufactured in the United States, it meets stringent quality controls and is backed by Conrader’s reputation for reliable industrial components. Whether you are retrofitting an older system or building a new air‑distribution network, this valve offers the confidence that your equipment will remain protected from over‑pressure events.

FAQ
What does a pop‑off valve do?
A pop‑off valve automatically releases excess pressure when the set limit (in this case 175 psi) is reached. This rapid venting protects compressors, tanks, and downstream components from over‑pressure damage, extending the life of the entire system.
Can this valve be used with oil‑free compressors?
Yes. The brass body and silicone rubber seat are compatible with both oil‑free and oil‑lubricated air systems. The valve’s design prevents oil migration, ensuring clean operation and reliable pressure relief regardless of the compressor type.
How do I install the valve correctly?
Start by turning off the air supply and relieving any residual pressure. Thread the 1/4‑inch NPT inlet onto the compressor outlet, applying thread sealant if desired for extra security. Connect the MNPT outlet to your vent line, ensuring the direction of flow is correct. Tighten both connections by hand and then give a quarter turn with a wrench to secure the seal.
What maintenance is required?
The valve is designed for low‑maintenance operation. Periodic visual inspections for corrosion or seat wear are recommended. If the valve fails to pop‑off at the calibrated pressure, replace the silicone seat or the entire valve to maintain safety performance.
Is this valve covered by a warranty?
Conrader provides a limited warranty that covers manufacturing defects for a specified period. Contact our customer service team with your purchase details for warranty verification and assistance with any replacement needs.
