The Copes-Vulcan DSCV is an angle style valve that combines pressure and temperature reduction. The DSCV is custom engineered for specific operating parameters. DSCV’s are generally used for applications where the valves typically remain closed for long periods of time to isolate steam flow.

FEATURES:

• High flow capacity to 9500 Cv
• Pressure class to ANSI Class 4500
• Unlimited inlet/outlet connections available
• Class V shut off available
• Multiple spray configurations available
• Valve trim serviceable in line through bonnet
• Low noise trim options including Raven and Hush styles
• Broad range of actuators to meet stroke time requirements
• Diffuser provided for additional noise and vibration control

The Copes-Vulcan PRDS Pressure Reducing Desuperheater is a single seat, angle style valve that combines pressure and temperature reduction in one compact solution.

The high pressure, high temperature vapor enters the main branch, is reduced in pressure and then coolant is introduced. The high velocities and turbulent flow conditions that are present immediately following the pressure reduction allow for rapid atomization and absorption of the coolant.

The PRDS Pressure Reducing Desuperheater is best suited to applications requiring continuous modulation.

FEATURES:

• High quality cast body
• Smooth body contours to reduce stress concentration
• Fully guided plug reduces wear
• Trim is fully accessible through the bonnet for ease of maintenance
• Solid valve stem eliminates thermal stress experienced in hollow stem designs
• Unique water mixing provides superior control and eliminates piping thermal liners.
