The YSRV01 Series Instrumentation Relief Valve is a compact and high-performance safety device designed to protect instrumentation systems from overpressure conditions. Engineered with precision and durability in mind, it automatically relieves excess pressure by venting when system limits are exceeded, ensuring safe and reliable operation. Its stainless steel construction offers superior resistance to corrosion, making it ideal for use in demanding environments such as chemical processing, gas sampling, and hydraulic control systems.
This relief valve features an adjustable pressure setting, available with soft or metal seat options to suit different media and application needs. With its space-saving design, standard 1/4" threaded connections, and ease of maintenance, the YSRV01 is well-suited for installation in confined spaces or on instrumentation panels. Whether used in laboratories, refineries, or industrial automation systems, the YSRV01 provides consistent performance and long-term reliability.
YSRV01 series relief valves are proportional relief valves that open gradually as the pressure increases. Consequently, they do not have a capacity rating at a given pressure rise (accumulation), and they are not certified to ASME or any other codes. Some system applications require relief valves to meet specific safety codes. The system designer and user must determine when such codes apply and whether these relief valves conform to them.
Instrumentation Relief Valve is trusted across various industries for its precision, durability, and reliability. Explore its wide-ranging applications below:
Gate valves are crucial in managing the flow of crude oil, natural gas, and refined products in pipelines and processing plants. They are widely used in both upstream (extraction) and downstream (refining and distribution) operations for reliable isolation and flow control.
Gate valves are essential in water distribution and treatment plants, providing isolation during system maintenance or repairs. They are installed in pipelines to efficiently manage water flow and ensure reliable system operation.
Gate valves are widely used in thermal and nuclear power plants, particularly in steam, feedwater, and cooling systems. They offer reliable isolation in high-pressure and high-temperature environments to ensure the smooth operation of power plants.
Gate valves play a vital role in controlling the flow of various chemicals and gases within pipelines in chemical and petrochemical plants. They are designed to prevent contamination and protect sensitive equipment.
Gate valves are used in pipelines managing raw pulp, chemicals, and water in the pulp and paper industry. They provide effective isolation during maintenance and operational control, ensuring smooth production processes.
In marine and offshore settings, gate valves are installed in ballast water systems, cargo lines, and fire protection systems on ships and offshore platforms. They help ensure safe and efficient operations in harsh marine environments.
Gate valves are used in various industrial manufacturing processes, including steel production, mining, and food processing, to handle a wide range of process fluids and provide reliable isolation and flow control.
Gate valves are commonly used in chilled water and condenser systems to ensure unidirectional flow. They help maintain system efficiency, protect pumps, and other components from damage, ensuring smooth operation in HVAC systems.

| 4000 to 5000 (275 to 344) | G | Red |
| 5000 to 6000 (344 to 413) | H | Green |
YSRV01 series valves are available with springs factory-set to a specified set pressure. Valves are set, tested, locked, and tagged with the set pressure.
R series relief valves OPEN when system pressure reaches the set pressure and CLOSE when system pressure falls below the set pressure.
For valves not actuated for a period of time, initial relief pressure may be higher than the set pressure.
