Relief valves & Pressure reducing valves
Selection of a valve of the correct size and loading is important since they have a narrow pressure range. Under normal conditions a relief valve should operate consistently within reasonable limits of its set pressure. Incorrect function may be due to the setting, valve seat deposit or damage. Relief valve seats should be checked whenever the pump is overhauled
since they have a narrow pressure range. Under normal conditions a relief valve should operate consistently within reasonable limits of its set pressure. Incorrect function may be due to the setting, valve seat deposit or damage. Relief valve seats should be checked whenever the pump is overhauled.
Pressure reducing valves
If it is necessary to provide steam or air at a pressure less than that of the boiler or compressed air reservoir, a reducing valve is fitted. This will maintain the downstream pressure within defined limits over a range of flow, despite any changes in supply pressure.
Any decrease in pressure on the outlet side, will allow the valve to be pushed open by the spring. Any increase will close it. It is important that this type of valve is installed in the vertical position.
The self-regulating valve can be replaced by an automatic process control valve for fluid pressure control as used for control functions in unmanned machinery spaces. This permits remote control of the set-point of the valve and by careful selection of valve trim (the control industry's term for the internal parts of the valve which come in contact with the controlled fluid and form the actual control portion) a variety of flow characteristics can be achieved.
Relief valves
Excess pressure is eased by a relief valve . This consists of a disc held closed by a spring loaded stem. The compression on the spring can be adjusted so that the valve opens at the desired pressure.
Key features
Steam passes through the extended drilled bonnet before being throttled though a cage type plug with multiple drilled holes which provides optimum characteristics for control of steam pressure.
Reduced maintenance cost and downtime
Complies with the following standards: SIL, ASME, PED, IBR, CRN, FaMA, MoM, Gost, ISO 9001/14001/18001
Applications
High pressure system
Vent to atmosphere, normally together with a silencer installed downstream
Pressure control where no desuperheating is needed
Steam conditioning applications where desuperheating cannot be integrated into the same valve
Low pressure system
Mainly designed for high pressure systems, but can also be used in low pressure systems
Process industry
IMI CCI recommends the VST-SE or the VLB for these applications???
