Control Devices ST25-1A200 Brass ASME Safety Valve 200 psi 1/4″ NPT

Description

Product Overview

The Control Devices ST25-1A200 is a precision‑engineered brass safety valve designed to meet the rigorous demands of modern industrial hydraulic and pneumatic systems. Constructed from high‑grade brass, the valve offers exceptional corrosion resistance, ensuring a long service life even in harsh environments. The internal stainless‑steel spring provides consistent pressure relief at the preset 200 psi set point, delivering reliable protection against over‑pressure incidents. With a maximum operating temperature of 250 °F, this valve maintains performance stability in high‑temperature applications, making it suitable for a wide range of processes including oil refining, chemical processing, and heavy‑duty manufacturing. The valve’s 1/4 NPT male threaded inlet facilitates straightforward integration into existing piping networks, while the ASME safety rating, complete with UV and NB marks, guarantees compliance with industry safety standards. Its compact dimensions—5 × 1 × 1 inches—and lightweight design (1.59 oz) allow for easy handling and installation in confined spaces.

Usage

Designed for versatility, the ST25-1A200 excels in environments where precise pressure control is critical. It is ideal for protecting compressors, pumps, and actuators in manufacturing plants, where sudden pressure spikes can cause equipment failure or safety hazards. The valve’s robust construction also makes it a reliable choice for high‑temperature fluid control in petrochemical refineries, where temperatures frequently exceed standard operating limits. In addition, its compact size and standard 1/4 NPT connection enable easy retrofitting into legacy systems, reducing downtime during upgrades. Whether used in a continuous production line or a batch processing setup, the valve provides consistent relief performance, helping maintain system integrity and prolonging the lifespan of downstream components. Its straightforward installation process means technicians can quickly replace or add the valve without extensive system shutdowns, improving overall operational efficiency.
