Detailed Description

Mahavas Precision Controls Pvt. Ltd. is seat tightness in a Flanged Piston Valve is obtained by a cylindrically shaped burnished piston, connected to a spindle, and operated by a hand wheel, which enables it to move through the inner diameter of two sealing rings. The two sealing rings are separated by a ported spacer. The bottom ring rests on a cast machined groove of the body and upper packing ring is being held and remained pressed by a bonnet on top. The bonnet rests on the top ring, when tightened evenly by the nut of the stud presses the spacer, which in turn presses the bottom ring. Flanged Piston Valve is done by keeping the valve in closed position. Thus the mechanism is aligned compressed and ready for operation.

 

When the piston is in the high position, that is, held by only the upper valve ring, (which also ensures tightness to the atmosphere), the valve is open. When the piston is lowered and is held in place by both the upper and lower valve ring (and thus ensuring seat tightness between the valve inlet and outlet), the valve is closed. Because of the use of the sealing rings, the piston valve is considered a "soft-seated", valve. The contact between the piston and rings (sealing effect) is positively assured by means of the pressure exerted by stud bolts. Spring washers (Belleville Type), are fitted to compensate expansion due to temperature variations.

Features:

  • Exceptional leak tightness across the part and to atmosphere
  • Seatless valve
  • Larger effective sealing area
  • Stays tight during thermal exception
  • Durability-Piston unexpected to media
  • Maintenance Friendly-Valve remains online during maintenance
  • Economic, saves energy & environmental friendly
  • Use as a regulating or modulating valve

The cast carbon steel piston valve is manufactured to ANSI class # 150 & 300 pressure rating. The PC piston valve is a seatless valve. In PC piston valve, seat and gland are replaced by lower and upper sealing rings. The unique design ensures a long life even at high temperature upto 427 ?.
