TSV manufactures an engineered lineup of Industrial Control Valve configurations for global oil & gas transmission pipelines, refinery manifolds, power plants, and severe industrial processes. Each unit undergoes 100% hydrostatic and pneumatic factory acceptance testing before dispatch.
Top-guided single seated globe control valve with multi-spring pneumatic diaphragm actuator and smart positioner for tight shut-off and high rangeability.
Balanced trim plug reduces actuator thrust requirements by 80%, handling large pressure drops without vibration or stem oscillation in power piping.
Twin seat rings balance dynamic hydraulic force on the plug, enabling very high flow rates and low actuator forces in district heating and cooling.
90-degree angle body geometry prevents impingement erosion on the downstream pipe wall in severe flashing and outgassing hydrocarbon lines.
Multi-ply hydroformed metal bellows eliminates packing stem leakage, fully compliant with ISO 15848-1 Class AH for lethal chlorine and phosgene gas.
Integrated intelligent linear electric actuator requiring zero compressed air supply. Features digital display, auto-tuning calibration, and Modbus RTU.
Heavy-duty electric actuator with thrust rating up to 45 kN coupled with a cage-guided balanced trim for precise regulation across severe pressure drops.
Engineered for micro-metering of chemical inhibitors, catalyst injection, and pilot plant laboratories with interchangeable precision needle trims.
Multi-turn tortuous path labyrinth disc stack divides pressure drop into numerous small stages, completely preventing aerodynamic noise and sonic vibration.
Extended thin-walled stainless column maintains stuffing box temperature within normal packing operating limits in LNG and cryogenic air separation.
