Newly developed with the foreign advanced technology ,the

pressure and temperature of the primary steam transported

from power station,industrial boiler and thermal power

plant.After treatment,the pressure and temperature of the

secondary steam can meet the technological requirement for

production.
Widely used in alumina industry ,electric power industry and

steel industry ,the industrical control valve can be classified into

pressure and temperature relief series ,temperature relief

series and pressure series.
Features
1.The integrated design effectively reduces the length of the

boiler pressure and temperature relief device.so the product

requires small instalation space .
2. Designed with heat dissipation structure and thermal

insulation device ,the valve deck of the pressure and teperature

reliefe valve prevent heat convection or rdiation.Therefore, the

normal operation of  the  actuator can be hereby ensured .
3.Produced with rapidly -installed valve body ,all the parts and

component can be disassembled even the valve body is not

dismantled .So the maintenance of the steam pressure and

temperature relief devices is easy and convenient.
4.With special treatment ,the throttle washer and valve disc will

not get deformed under high temperature, The state operation

makes for outstanding guiding performance.
5.Every two orifices of the pressure and temperature relief

valve are symmetric to each other.The medium throtting is

completed with certain distance from sealing surface and the

valve body .
6.To reduce the operating force, the valve disc of the power

station pressure and temperature relief valve is offered with

balanced structure.
7.Besides noise reduction ,the silencer is conductive to

secondary pressure relief.Moreover,the desuperheating water

can be prevented from spraying to the valve body .
8.The pressure and temperature relief valve is offered with

mechanical atomizing nozzle.By ultilizing the spinning disc and

the small holes ,the desuperheating water can be fully atomized

inside the valve body and mixed with the steam.
9.In case different pressure is required,the throttle orifice can

be installed at the outlet to realize the third -level pressure

relief ,or even fourth-level pressure relief.More ,the throttle

orifice is capable of turning the turbulent current into laminar

flow.
