Rotary Control Valve with tight shut-off and high grade rubber seat ring.
GENERAL:
With a specially designed rubber seat ring, the model 508V ensures tight shut-off and eliminates the need for any additional stop valve that is normally required by conventional control valves.
STRUCTURE:
TIGHT SHUT-OFF WITH A RUBBER SEAT RING:
The 508V valve has a reinforced core rubber seat ring allowing it to be used for high pressure services up to 16 bARg with complete tight shut-off. Except for the rubber seat ring, the 508V has the same design principles as the 507V where excellent controllability is achieved by having the innovative teethed disc seating arrangement.
NO ADDITIONAL STOP VALVE MEANS LESS INSTALLATION SPACE AND LESS COST:
Because of its reliable sealing properties against a high differential pressure, the 508V valve does not require any additional stop valve, saving on cost and installation space.
