The PRS6 is a three-way pressure reducing valve that has been developed to give reduced pressure in a particular part of the hydraulic system. The valve maintains the secondary pressure setting constantly, regardless of pressure variations on the primary side. Common applications include pilot circuits in hydraulic and electro-hydraulic servo systems.
Compact and easy to install
Easy to adjust within respective pressure range
Can be factory set and sealed to prevent unauthorized pressure changing
Highly suited for use as a reducing valve in pilot circuits where the pilot pressure is taken from the main circuit

In many paper mills steam is superheated and distributed at high pressure for efficiency reasons. The pipe sizes required to transport the high pressure steam are smaller due to the low specific volume of the steam, and turbine efficiency is optimized when high pressure superheated steam is used. Kadant Johnson desuperheaters are designed to reduce the temperature of superheated steam for optimal heat transfer and efficiency.

The Copes-Vulcan Multiple Nozzle Spray Desuperheater offers optimum performance and rangeability in a variable spray tube design. The MNSD fills the performance gap between the limited capability of a simple mechanical spray type desuperheater and the virtually unlimited capability of Copes-Vulcan’s Variable Orifice Desuperheater. The MNSD offers high temperature capabilities and up to Class V leakage rating.
Features:
- Temperature control to within 15°F (8°C) of saturation with the ability to hold set point within a tolerance of 10 °F (6°C)
- Standard maximum available Cv of 10.5 (Kv of 8.9)
- Water flow turndown of 150:1 or higher
- User friendly design - nozzles and trim assembly can be removed without disconnecting the actuator
- No need for separate cooling water control valve
- Designed for applications with temperatures up to 1150°F (620 °C)
- Available in standard classes 600, 900,1500 and 2500 per ANSI B16.5
- Cooling water inlet pressures up to 3500 psig (24 MPag)(higher pressures on application)
- FCI 70-2/ANSI Class IV or Class V shutoff capability
- Suitable for vertical or horizontal installation
- Standard ANSI connections are 3" (80mm) raised face flange (steam) and 1.5" (40mm) raised face flange (water)
