The DSV® Check Valve Cut Sheet gives you in-depth detail about the values.
A spring-assisted, non-slam check valve, the DSV® Check Valve prevents flow reversal in systems to meet the most stringent cleanliness codes in various industries. Using a 316L stainless steel body and seat, along with an internal surface finish of 25 Ra, the DSV® Check Valve offers easy access to the internals through a quick release clamp and elastomeric body seal. The disc and seat are lapped to provide the tightest possible level of shut off.
The DSV® Check Valve is available for both “vertical” and “horizontal” orientations, which allows the valve to accommodate all possible piping arrangements. When a horizontal line needs a self-draining valve, the “horizontal” model of the DSV® Check Valve is appropriate. In the case of a vertical line requiring a self-draining valve–or a horizontal line that doesn’t require self-draining–the “vertical” valve is more commonly specified.
Eight sizes of the DSV® Check Valve are available, ranging from ½’’ all the way up to 4’’. Sizes for an edge-guided disc range from ½’’ to 2’’, while an edge/center-guided disc ranges from 2 ½’’ to 4’’. The springs used in this check valve offer low cracking pressures, a conical design, and electropolished finish.
The standard body seal on the DSV® Check Valve is EPDM, however Tuf-Flex® and Viton® are available as optional finishes. Also, a 15 RA electropolished internal finish is available instead of the standard 25 Ra finish. This check valve can be cleaned in place, and has clamped ends for ease of maintenance and installation.
