Safety Valve Supplier in USA 

SVR Global is a Safety Valve Supplier in USA, delivering valves designed to protect equipment, pipelines, and pressure vessels from overpressure conditions. Our safety valves are widely used in industries across Houston, Texas, California, New York, and other regions, ensuring operational safety and compliance with international standards. 

What is a Safety Valve? 

A safety valve automatically releases pressure from a system when it exceeds a ideal value limit. These valves act as the final line of defence, preventing equipment failure, explosions, or hazardous leaks caused by overpressure. Safety valves are critical in industries where steam, gas, or liquid systems must operate within safe pressure limits, making them essential for both plant safety and regulatory compliance. 

Functions and Working of Safety Valves 

Functions of a safety valve include: 

  • Pressure Relief – Helps in Releasing excess pressure from the system to avoid accidents. 
  • System Protection – Safeguards pipelines, boilers, and pressure vessels. 
  • Operational Reliability – Maintains consistent pressure levels for smooth performance. 
  • Regulatory Compliance – Ensures adherence to safety codes and industry standards. 

Working Principle 

Under normal system conditions, a safety valve remains tightly closed. When internal pressure climbs above the valve’s set limit, the spring force holding the disc in place is overcome. The disc lifts, allowing fluid or steam to escape and relieving excess pressure. Once the system stabilizes and pressure drops back to a safe range, the spring pushes the disc onto the seat again, automatically closing the valve and restoring normal operation. 

Key Components of a Safety Valve 

  • Body – Manufactured in materials such as cast steel, stainless steel, or alloy steel to withstand high pressure. 
  • Inlet and Outlet Connections – Provide a controlled path for pressure discharge. 
  • Disc and Seat Assembly – Maintain a tight seal when the valve is closed. 
  • Spring Element – Keeps the disc in position until the pressure reaches the pre-set value. 
  • Bonnet and Lever (Optional) – Offer structural support and, in some models, allow manual release of pressure. 

Types of Safety Valves Supplied 

SVR Global offers several types of safety valves in the USA to meet different industrial needs: 

  • Spring-Loaded Safety Valve – Widely used in steam and gas systems for dependable pressure relief. 
  • Balanced Bellows Safety Valve – Maintains accuracy in systems where backpressure is present. 
  • High-Temperature Safety Valve – Built for boiler and steam service where extreme heat is involved. 
  • Low-Pressure Safety Valve – Applied in tanks and low-pressure vessels where sensitive relief is required. 

Applications of Safety Valves in USA Industries 

Safety valves are widely applied in industries where pressure control is critical: 

  • Oil & Gas Refineries – Protecting storage tanks, pipelines, and compressors. 
  • Power Plants – Steam boilers and turbine systems. 
  • Petrochemical Facilities – Preventing overpressure in chemical reactors and pipelines. 
  • Water Treatment Plants – Pressure regulation in pumping and distribution systems. 
  • Pharmaceutical and Food Processing – Ensuring safe operation in sterilization and process heating. 
  • General Manufacturing – Protecting equipment in compressed air and hydraulic systems.
