Class TH-High Pressure Reducing Valve-江苏弗里森流体工程技术有限公司

The Class TH High Pressure Reducing Valve, has been
developed to extend the range of the Class T & TLP.
Our new Class TH is now able to operate with higher outlet
pressures.
Extended pressure offering:
• Maximum 20 Barg (290 Psig) outlet pressure.
The Class TH is a balanced direct acting pressure reducing
valve and is designed for applications that have varying inlet
pressures and capacities, requiring positive “shut-off” under
no flow conditions.
All Bailey valves are manufactured to the highest levels of
quality and the Class TH is no exception. It is manufactured
to the ISO9001 quality standard and is CE certified where
required within the PED.
The Class TH is a self actuated valve that requires no
external power source. This, along with its simple design,
allows the valve to be easily maintained and serviced, without
being removed from the line.

DIMENSIONS
The Class TH High Pressure Reducing
Valve, has been developed to increase the
outlet pressures available from the Class T
range of valves.
The existing range utilises diaphragm
technology to regulate the closing
pressure. This technology relies on the
flexibility of rolling rubber diaphragms,
which limit the maximum outlet pressure
due to the strength of the rubber.
Within the Class TH High Pressure
Reducing Valve, the diaphragm is replaced
with a piston (Y). The outlet pressure is
sensed up through port (X) to the
underside of the piston. This design allows
much higher pressures to be
accommodated and is less susceptible to
pressure spikes and water hammer.
