Model 100-CV - Solenoid-Operated Control Valves

Product Brand: Target Rock

solenoid control valve responds to standard plant control signals, throttling flow to meet exact plant requirements. 

 

SOLENOID CONTROL VALVE PRODUCT DETAILS

Target Rock is unique in the world in the technology of providing true modulating flow control for water, steam, and gas from a solenoid operated valve. The system consists of a pilot-operated solenoid valve, an LVDT for position indication, and a proprietary electronic positioner to create a closed feedback loop that responds to standard plant control signals to throttle flow to meet exact plant requirements. 

 

This technology is particularly well suited for emergency applications where a dependable and/or safety-grade pneumatic supply (required for traditional air-operated control valves) cannot be provided or is too expensive to install and maintain. 

 

At Curtiss Wright you’ll find a variety of different industrial valves such as ball valves, butterfly valveschangeover valves, check valves, control valves, directional control valvesgate valvesglobe valves, plug valves and pressure relief valves.

 

These valves are used in all industry segments. To find out more, read the related documents to find further information and product related assemblies, qualifications and capabillities.

TYPES OF SOLENOID CONTROL VALVES

  • Direct acting valves
    • In direct acting valves, a coil magnetically opens the valve, lifting the plunger and the seat of the valve without depending on exterior pressue.
  • Pilot-operated valves
    • In pilot-operated valves, the solenoid activates a significantly smaller pilot valve, which then opens a larger valve operating at much higher pressue.
  • Two-way valves
    • On a two-way valve each port is alternately used to allow flow as well as close it off. In its operation, a two-way valve can be specified to be either "normally open" or "normally closed."
  • Three-way valves
    • A three-way valve comes with three ports, these are commonly used when alternate and exhaustive pressue are required.
Principles of Solenoid Valve Operation

Unique technology allowing for the fastest response

Target Rock Modulating SOVs eliminate the need for pneumatic systems. In addition, this unique technology has all moving parts inside the static pressure boundary with no stem, packing, or bellows seal. This eliminates friction, allowing the valve to respond quickly to flow demand, and hermetically seals the process fluid to eliminate leakage paths to atmosphere.

WHAT IS A SOLENOID CONTROL VALVE?

solenoid control valve ian electro-mechanical control unit that is normally used to control and direct the flow of liquid. When the control valve switches between energized or de-energized, this will either allow fluid or gas to flow or shut off from the core tube. Solenoids are highly reliable with long service life and offer way of fast and safe switching. 

 

piloted solenoid valve provides high flow rates and can operate at higher pressure and temperature range, with lower power consumption.

 

HOW DO SOLENOID CONTROL VALVES WORK?

 

Solenoid valves are used to control the flow of fluids or gases, by opening or closing an orifice in the valve body to release, shut off, mix, direct or distribute fluidsThe orifice is controlled by a plunger which is raised when energised or lowered when de-energised, this is achieved by energising the solenoid coil within a core tube.   

 

WHERE ARE SOLENOID CONTROL VALVES USED?

 

Solenoid valves are used in many different industrial applications such as fluid power motors, pneumatic and hydraulic systemscalibration stands and various others. 

 

To name a few sectors where solenoid valves are used: 

 

  • Plant control loops 
  • Process control systems 
  • General on-off control 
  • Pressure relief and drainage 
  • Transport and tank facilities 
  • Oil and gas burner temperature controls   
  • Treatment of drinking water 
  • Machine and plant engineering  
  • Fire protection and extinguishing systems  
  • Fuelling supplies
