Comprehensive Guide to Safety Valves in China

Safety valves are critical components in various industrial applications, ensuring that systems operate safely under pressure. They prevent overpressure situations that can lead to catastrophic failures, protecting both equipment and personnel. As China’s manufacturing sector continues to expand, the demand for reliable safety valves has surged. This guide explores the different types of safety valves, their technical features, and key manufacturers in China.

Understanding Safety Valves

A safety valve is a mechanical device designed to automatically release pressure from a system when it exceeds a predetermined limit. This action prevents potential hazards such as explosions or equipment damage. Safety valves are essential in industries like oil and gas, petrochemicals, and power generation.

Technical Features of Safety Valves

The effectiveness of safety valves is determined by several technical features. Below is a comparison table highlighting these features:

Feature	Description
Set Pressure	The pressure at which the valve opens to release excess pressure.
Flow Capacity	The maximum flow rate the valve can handle when fully opened.
Material	Common materials include stainless steel, bronze, and carbon steel.
Temperature Rating	The maximum temperature the valve can withstand without failure.
Connection Type	Types include threaded, flanged, and welded connections.
Actuation Type	Can be spring-loaded, pilot-operated, or balanced bellows.
Standards Compliance	Compliance with international standards like API, ISO, and ASME.

Types of Safety Valves

Safety valves come in various types, each suited for specific applications. The following table summarizes the main types of safety valves:

Type	Description
Spring-Loaded Safety Valve	Utilizes a spring mechanism to maintain closure until the set pressure is reached.
Pilot-Operated Safety Valve	Uses a pilot valve to control the main valve, allowing for higher flow rates.
Balanced Bellows Safety Valve	Features a bellows design that minimizes the effect of back pressure on the valve.
Thermal Relief Valve	Designed to relieve pressure caused by thermal expansion in closed systems.
Pressure Relief Valve	Opens to relieve pressure in systems like boilers and pressure vessels.
