Pressure Relief: The valve is specifically designed to provide reliable pressure relief, preventing equipment damage and potential hazards.
Rotary Design: The rotary mechanism allows for smooth operation and accurate pressure control.
Adjustable Set Pressure: The valve is equipped with an adjustable set pressure feature, enabling customization based on system requirements.
Wide Pressure Range: The 225-7 valve can accommodate a broad range of pressure settings, making it versatile for different applications.
High Flow Capacity: The valve offers excellent flow capacity to handle large volumes of fluid or gas during relief situations.
Compact Size: The compact design of the valve allows for easy installation even in space-constrained environments.
Corrosion Resistance: Constructed from high-quality materials, the valve exhibits excellent resistance to corrosion, ensuring long-term durability.
Low Maintenance: The valve is designed for minimal maintenance requirements, reducing downtime and operational costs.
Working Principle:
The 225-7 Rotary Relief Valve operates based on the principle of spring-loaded pressure relief. When the system pressure exceeds the set point, the pressure acts on the valve disc, causing it to lift against the force of the spring. As the disc lifts, it creates an opening, allowing the excess pressure to escape. Once the pressure returns to the set point, the spring forces the disc back into the closed position, sealing off the relief path.
Construction:
Valve Body: The valve body is typically made of high-strength materials such as stainless steel or brass to withstand high pressures and provide corrosion resistance.
Rotary Disc: The disc is precisely machined to ensure a tight seal against the valve seat when closed and provide smooth rotary motion during relief operation.
Spring Assembly: The spring assembly applies the necessary force to keep the valve closed and determines the set pressure of the relief valve.
Seals and Gaskets: The valve incorporates seals and gaskets to prevent leakage and ensure a reliable seal between the moving parts.
Performance Characteristics:
Set Pressure Range: The 225-7 valve can be adjusted to relieve pressure within a wide range, typically between 10 psi (0.7 bar) and 1000 psi (69 bar), accommodating various system requirements.
Flow Capacity: The valve offers a high flow capacity, typically ranging from 50 GPM (189 LPM) to 2000 GPM (7571 LPM), enabling efficient pressure relief for different flow rates.
Response Time: The valve responds quickly to pressure changes, ensuring rapid relief and minimizing the risk of system damage.
Leakage: The valve is designed to provide a tight seal, minimizing leakage during both normal operation and relief situations.
Temperature Range: The valve can operate reliably within a wide temperature range, typically from -40°F (-40°C) to 400°F (204°C), allowing for versatile application in different environments.
