Piston Valve Cast 65-200mm (SPL)

Piston Valve CastPiston Valve Cast 65-200mm (SPL) 1Design Features:

Though sealing principle remains same as valve size 15mm to 50mm, pressure acting on large size Piston has been compensated in order to reduce the operational torque. Therefore, Piston is modified to have media pressure same at below and above Piston. This means, effect of media pressure on Piston is nullified thereby making valve operation easy.  Two main rings act as seal across ports and two similar rings but small size act as seal to atmosphere. There is one more ring between body/bonnet joint.
