and allows for fast, safe, environmentally-friendly venting and draining of piping systems. Safe depressurization is achieved in just one drip of fluid.
The SaVD Safe Vent Drain is available in ½” through 2” sizes, through ASME 2500 pressure class with NPT, butt weld or socket weld ends. Standard materials include Stainless Steel SA182-F316, A105 and F22. The SaVD features a HILTAP metal-to-metal wedge safety connector with two dynamic sealing surfaces, compact profile, ultra-safe residual pressure venting, and quick connectability to a gravity drain hose. The coupling locks under line pressure. Locking threads are located outside wetted volumes. Valve-mounted couplings may be steam cleaned and pressure-purged. Hooking up the SaVD with a matching HILTAP drainage pipe minimizes downtime, labor and environmental cleanup expense. The SaVD replaces low pressure bull plugs and screwed caps. The safe drain vent is manufactured to ISO 9001-2000 with full material traceability. CRN registration is available.

The Rationale Behind Valve Characteristics
Back in the “early days,” we were taught that, to properly control flow, we should select a linear valve characteristic when the valve controls more than 25% of the piping system pressure drop at full flow.
