Cone closure KVP
The MAHR cone closure makes pressure-tight seals of material filling openings. The main application area is the sealing of high pressure discharge vessels in high pressure conveying systems.
Case: grey cast iron, cast stainless steel
Flange: steel, 1.4301, 1.4571
Sealing cone: grey cast iron, cast stainless steel
Sealing ring: groove ring made of Hydrofit, Teflon, Viton
The cone closure consists of the case with sealing cone and the drive. The joined parts are sealed in each case with O-rings. The sealing cone is opened and closed using a lever design and a pneumatic cylinder. The seal is made by pressing the cone against the groove ring inserted in a steel ring.
The pneumatic drive is equipped with a 5/2 way solenoid valve. The cone closure has a limit switch in each end position for standard signalling.
control pressure: min. 3.5 bar
operating pressure: max. 16 bar
Absolute leak tightness as the tank interior pressure supports the seal due to the design. Low wear as the sealing ring does not come into contact with the material flow.
