Sh series superheated steam trap valves
Sh series superheated steam trap valve
The largest pressure：62kg/cm2, The largest displacement 5,134kg/h sh series bimetalic steam trap valve is the ideal trap valve for superheated or low-loading working conditions, the useful life is longer than other types of trap valve.
Advantage
well-knit
light in weight
applying to high-temperature
applying to high-pressure
longer useful life in superheated conditions
easy to maintain online
possessing fail-open function
water-attack-resistance
possessing many kinds of adapter and connecting specification
the internal is installed with filter
large start-up loading
silent drainage
no sensitive to the length of the connecting pipe
corrosion-resistance material of stainless steel(SH-900 type)
SH Series bimeralic trap valve can start drainage with large-loading at superheated conditions. Unique bimetalic components can rigorly shut off the trap valve before the superheated steam come into the trap, preventing lossing steam. SH Series are installed with Ti Disc and seat, it can ensure long useful life under superheated steam system scurviness working conditions.
Technical features
The trap is made of investment casting carbon steel(SH600 TYPE) and investment casting stainless steel(SH900TYPE), internal stainless steel filter can be maintained online. Steam trap is installed with laminate Ni-Cr bimetal mechanism and Ti Disc and seat, can be applicable to low-loading superheated working condition within authorised pressure range.

Model-selection
Main rule of selection：
1． loading of condensed water kg/h(confirming displacement )； 2． the selecting safety factor generally is between two and three；
3． Pressure difference MPa； 4. the max. permitting pressure MPa。
Order:
1、Supplying model ；2、Supplying connecting dimensions(if flange-connection is required, please supply the detail flange type ).
