Superior Throttling Capability:
Multi-turn stem design provides fine flow modulation, ideal for steam, condensate, or chemical dosing systems.
Low cavitation risk compared to gate or ball valves.

Bubble-Tight Shutoff:
Conical or parabolic plug profiles ensure leak-proof closure under high differential pressures.
Metal-to-metal or soft (PTFE/Graphite) seating options for varied media compatibility.

Durable Construction:
Bodies in cast steel (WCB), stainless steel (CF8M), alloy steel, bronze, compliant with BS 1873, BS 5352 (compact design) and ANSI B16.34 standards. Bolted bonnet or pressure-seal designs for high-temperature/pressure services.

Common Applications:

• Power Generation: Boiler feedwater control, turbine bypass.
• Oil & Gas: Refinery process lines, pressure relief bypass.
• HVAC: Chilled water balancing, heat exchanger control.
