Profile: ESME Valves Ltd. specializes in the manufacture of valves and actuators. We are a BS EN ISO 9001:2000 certified company. Our products include pilot operated pressure regulators, control valves, self-acting pressure reducers, and direct pilot operated pressure regulator for petrochemical, chemical, power, gas, and process industries. We also manufacture self actuated pressure regulators, air pilot operated pressure, and direct pilot operated pressure regulators. Our main valve is globe, single seated type with V-port plug piston-operated & controlled by a pilot appropriate to the pressure and service. Our pilot construction is similar for pressure reducing or back pressure control. Our screwing seat clockwise viewed from the seat end increases the sensitivity and reduces the proportional band of the regulator pilot valves for differential service, and have '0'-ring sealed adjusting screws. We supply with double diaphragm construction to ensure separation of the line, and spring chamber loading fluids in the event of diaphragm rupture. We mainly offer cryogenic service with material and non-destructive testing.
