Presenting model 1001 a self-acting, pilot and piston operated pressure-reducing valves, a popular choice for pressure reduction of steam in all types of industries. It operates on spring balance principal and the downstream pressure is sensed below the diaphragm that is balanced by the spring tension. Increasing spring tension increases outlet pressure and vice versa. Features: special quality stainless steel diaphragm; maintains constant outlet pressure, irrespective of change in upstream pressure [low droop]; high turn down ratio; full to 10% [10:1]; very idial for low and medium pressure, steam, gas and air; and a variety of spring range for better downstream pressure control
