DOUBLE DISC VALVE / PRESSURE EQUILISING VALVE
HRI Double Disc valves were designed to for on/off service in venting and conveying lines on high pressure pneumatic conveying applications. The design is rugged and clean operating. The Double disc valve has metal to metal sealing to reduce wear in venting and discharge applications. The internal linkage drives the two spring loaded disks against the lapped body endplates. The disks move along a unique path and rotates with each stoke of the air cylinder which distributes the wear evenly and extends the life of the disks and endplates. HRI Double Disc valve can be shipped pre-piped.
Feature and Benefit
Unique Internal Linkage
Extends life of disk by distributing the wear uniformly around its circumference.
Hardened Stainless Steel Disc and Seat
Excellent corrosion and long service life
Lapped Body End Plates and Spring Loaded Disks
Allow disks to slide on body end plates which minimizes build Up and extends life.
Removable and Grease able Packing Arrangement
Easy to maintain and extend bearing life
Pressurizing Body Kits
Pressurizes the body with conveying air which improves sealing in venting applications and prevents material from accumulating in the body in conveying line applications.
