DFT® HI-100™ Severe Service Control Valve

DFT® HI-100™ Severe Service Control Valve


The HI-100™ features an in-line Straight-thru, venturi flow design. The seating element, a spherical ball, is contained by a cage that positions it relative to the downstream seat by means of linear stem travel. There are no close clearances between the moving parts (i.e. cage, ball and seat). These features enable the valve to operate smoothly and efficiently at high or low temperatures, and/or in fluids carrying suspended particles such as slurries. The Quick Change Trim feature permits in-line replacement of the internal trim (ball, stem, cage, seats, seat retainer cartridge and wear bushings). Interchangeability of the upstream and downstream seats and wear bushings extends the life of the valve at no extra cost.
DSV® Sanitary Check Valves

DSV® Sanitary Check Valves

(14)
The DSV® is an in-line spring-assisted check valve designed to prevent flow reversal in industries with strict cleanliness codes. To accommodate various piping arrangements, the DSV® is available as a "Vertical" or "Horizontal" valve. The Horizontal valve is for Horizontal lines requiring a self draining valve. The "Vertical" design is for "Vertical" installations and "Horizontal" lines when a self draining valve is not required. The DSV®, with a 316L stainless steel body and seat, is fastened with a quick release clamp and elastomeric body seal to permit fast and easy access to the internals. The internal surface finish is 25 Ra while the disc and seat are lapped to provide excellent shutoff.
