The Copes-Vulcan DSCV is an angle style valve that combines pressure and temperature reduction . The DSCV is custom engineered for specific operating parameters.
DSCVs are generally used for Turbine Bypass 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

Superior Turbine Tripping Reliability
The Elliott Pos-E-Stop 203 Trip Block is a technological leap forward in the control of trip valves for steam turbines, hot gas expanders and similar power applications in emergency situations such as overspeed, high vibration or process upset. The Pos-E-Stop Trip Block's flexible "two-out-of-three" logic provides a significantly higher degree of tripping reliability than single or paired solenoid designs, and its best in class response time reduces the tripping interval for enhanced safety. And, the Pos-E-Stop Trip Block has the ability to interface with the master plant control or EDS system.
Features and Benefits
- Improved trip system reliability
- Best in class response time with reduced tripping interval
- Increased availability
- On-line test capability without defeating trip protection
- On-line replacement of critical components without defeating trip protection
- Continuous on-line monitoring of solenoids and valve positions
- Elimination of isolation valves reduces risk of operator error
- Enables trip system standardization across the plant
- Easy to install; simplifies most piping layouts
- Meets hazardous area classifications
- Meets applicable CE directives

Alcon 2-way Special Purpose Steam Solenoid Valves feature a wide range of available products. With a choice of brass or stainless steel body, these valves are specifically designed for steam service up to +356°F. Valves are offered in NEMA enclosures with wire or DIN electrical connection.
|
|
APPLICATION:
To control the flow of STEAM. Steam must be free of sediment. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
OPERATION:
Valve opens when energized and closes when de-energized. When the coil is energized the pilot valve opens, relieving the pressure above the piston, which is then lifted from its seat by the plunger. Upon de-energizing the coil, a spring closes the pilot valve and opens a bleed passageway to permit pressure to build above the piston and seat it.
