Product Details
what is a safety valve?---Safety Valve Definition
The safety valve is a valve that plays a role of fail-safe protection. An
example of a safety valve is a pressure release valve, which automatically
releases substances in a boiler, pressure vessel, or other system when the
pressure or temperature exceeds a preset limit. The pilot operated safety valve
is a special type of pressure safety valve. A leak-proof, lower cost, single
emergency use option is the rupture disk.

How does the safety valve work?
The safety valve is used to prevent the pressure increase from causing
malfunction, fire or explosion. The safety valve has only mechanical parts, so
it is used when the electronic or pneumatic safety device fails. The safety
valve is completely driven by the medium of the system and keeps working in the
event of a power failure.
Safety valves play an important role in ensuring the safety of personnel and
equipment. Building on the long-term legacy of comprehensive safety valves, we
work closely with customers and regulatory agencies to configure, design and
manufacture safety valves to help maintain safer operating conditions in
various environments.

How many types of safety valves are there?
There are mainly two types of safety valves. Spring type safety valve and pilot
type safety valve.
Spring safety valve
The spring force Fs is transmitted to the plate that closes the nozzle through
the main shaft, and the plate is closed together to ensure sealing. As long as
the spring force is greater than the force Fp generated by the valve inlet
pressure, this situation will remain.

Pilot operated safety valve
The pilot operated safety valve limits the pressure in the system by opening
the main valve to compensate for overpressure. They are self-medium controlled.
Like all medium-load safety valves, both sides of the sealing disc have the
same pressure effect. However, due to the different size of the surface, a
greater force is generated in the closing direction.

What is the difference between a safety valve and a relief valve?
Although both terms refer to valves used to release pressure from pressurized
systems, their technical definitions are slightly different.
Safety Valve vs. Relief Valve
Generally speaking, the term overflow valve refers to the opening of these
valves used to control the pressure in the pressurized system. It is usually
used in fluid or compressed air systems and is proportional to the increase in
system pressure. The valve that makes the system achieve the best function .
The design of the safety valve can help your equipment to avoid system
failures, to be fully opened immediately to avoid disasters, and to protect the
equipment from overpressure conditions. Not to control the pressure of the
