Applications

Stainless Steel High Pressure Relief Valve

A safety valve's purpose is primarily for industrial applications to protect against overpressure, which can cause dangerous situations such as fire or explosions. Industrial safety valves are often found in:

Oil, Gas, And Petroleum Industry
For example, subsurface safety valves, or downhole safety valves, are common on offshore oil wells. In the case of equipment malfunction, a safety valve can shut off rapidly to prevent oil and gas from flowing up the well in unsafe conditions.

Energy
Safety valves in power plants are common for compressible gasses such as steam and air.

Sanitary
Stainless steel safety valves are ideal for industries that require sanitary conditions. For example, in the food, beverage, and pharmaceutical industries.

HVAC
Safety valves relieve pressure in the case of blocked discharge, thermal expansion, or external heat that can damage the components.

Introduction to Safety Valve Types

Safety Valve Type	Description	Application
Spring-loaded Safety Valve	Uses a spring to maintain valve closure; Opens when pressure exceeds set value	Boilers, pressure vessels, pipelines, oil & gas systems
Pilot-operated Safety Valve	Utilizes a pilot valve to control the opening and closing of the main valve	Large pressure vessels, petrochemical processes, power plants
Pressure and Vacuum Relief Valve	Provides both pressure and vacuum relief to prevent overpressure or vacuum conditions	Storage tanks, silos, process equipment
Balanced Bellows Safety Valve	Employs a bellows to balance the pressure and maintain consistent set point	High-pressure steam systems, corrosive environments
Rupture Disk Safety Valve	Consists of a disk that ruptures at a specific pressure, allowing pressure release	High-pressure, high-temperature applications
Diaphragm Safety Valve	Uses a diaphragm to control the opening and closing of the valve	Pharmaceutical, food processing, and hygienic applications
Pilot-operated Pressure Vacuum Valve	Combines pressure and vacuum relief with a pilot valve control	Bulk liquid storage, transportation, chemical processing
Thermal Safety Valve	Responds to changes in temperature in addition to pressure	Steam systems, thermal oil heaters
Dead Weight Safety Valve	Utilizes weights to control valve opening at a predetermined pressure	Laboratory equipment, low-pressure applications
Electromagnetic Safety Valve	Operates through an electromagnetic actuator	Automation systems, precise pressure control
