Valve Applications: CH=Check Valves, TT=Throttle Trip Valves, PV=Plug Valves, PR=Pressure Relief Valves, ALL=All Valves, 3W=Three Way Valves
- Three-Way valve used in feedwater heater bypass (3W)
- Reverse flow prevention in process line (CH)
- Turbine protection as bleeder non-return valves for electric utilities. (CH)
- Feedwater heater bypass (CH)
- Installed in turbine extraction pipelines that supply steam to feed water heaters, auxiliary turbines and other equipment (CH)
- Steam turbine start-up and shut-down (TT)
- Steam turbine emergency protection (TT)
- Isolation of oil coolers in power plant systems (PV)
- Equipment protection from over-pressurization (PR)
- System protection from pressure surges (PR)
- Used in Power industry – coal, gas-fired, combined cycle, nuclear, geothermal and solar plants (ALL)
- Used in natural gas combined cycle plant for steam extraction and cold reheat non-return (CH, TT)
- Extraction check valve supplied with designs for either horizontal or vertical pipeline (CH)
- Designed and manufactured in accordance with API 611 & 612, NEMA SM23/24, ANSI B16.34 and B16.5, and ASME Section VIII (ALL)
- Extraction steam stop valves and non-return valves are used to protect the main turbine from overspeed and from water entering the turbine (ALL)
- Used in refineries and petrochemical plants for compressor protection, fluid catalytic cracking air blower discharge, compressor discharge lines and in process applications (CH)
- Extraction check valves are located at extraction connections and are capable of closing within an appropriate time limit to prevent reverse flow and maintain stable turbine speeds in the event of a turbine generator trip signal (CH)
- Used in cold reheat line preventing reheat steam from entering turbine exhaust line in the event of turbine trip (CH)
- To prevent backflow of steam from feed water heaters, auxiliary turbines and other equipment to the main turbine after sudden load reductions or turbine trip (CH)
- Effectively used on compressor discharge lines and discharge lines of ethylene compressor, wet gas compressor as well as air compressors in refinery and hydrocarbon units (CH)
- Where reverse flow is desired, the valves can be configured to remain open until closed by a cylinder actuator on signal (CH)
- Widely used in chemical and petrochemical plants in reactor emergency shut off, compressor kick-back, and suction check (CH)
