Globe Valve
Globe Valves :
Heli Engineers Offer “KDLAAC” Cast Steel Globe Valves with 150, 300 class which are precisely made by using High Quality Raw-Materials.
These valves are OS and Y Type, Out side Screw and yoke, Rising Spindle and Hand Wheel Bolted Bonnet Designed Which ensure 100 % Smooth
Flow area and reduce pressure drop across the Valve.
Specially Designed Grafoil Rings in the Stuffing Box provides sure Tightness and Longer Packing life in Higher Temperature Applications also. Properly Machined and Lapped Back Sheet facilities are provided for Replacement of Gland Packing When Valve is on line & Under Pressure. Spiral Gaskets are also provided for zero leakage Applications.
