VD-FLUX - DETRON

DETROITFLUID POWERVD - Flux *Piston Type Universal Flow Distribution Valve* PATENT PI 9702874-6 JUNE 2, 1997The Piston Type Universal Flow Distribution Valve (VD-Flux*) has been developed and designed for steam flow or condensatecontrol in purge stations.On installation of bleeding points in steam lines, it allows:1) Flooding test. Discharge to the atmosphere before the steam trap (upstream)2) Leakage test. Discharge to the atmosphere after the steam trap (downstream)3) Steam trap isolation for maintenance and / or replacement.4) Normal operation. Recovery of condensate to the return line.CONSTRUCTION FEATURES1 9 8 7 6 12 3 4 51) - Ergonomic Rilsan coated (thermal protection) handles,available in the following colors: blue (bleeding), and red (process).2) - Trapezoidal thread allows less torque, reducing the valve openingand closing time.3) - Ascending (and descending) one-piece integral piston type stemdoes not require strength for tightness.4) - Contact between piston and packing does not require strengthfor tightness comparing to the metal-to-metal convetional systems.5) - Plate spring fits on the packing with safe and accuracy, keepingconstant pressure, assuring a perfect sealing performance.6) - Grafoil packing reinforced with stainless steel plates, allowing the valve to work in high temperature conditions and alsoincreasing the valve service life.7) - One-piece body, made of stainless steel, saves line spacing, allowing a long service life and installation in any piping direction.8) - They can be supplied with either threaded (NPT or BSPT)or weld ends.9) - The orifice is larger than the conventional ones (needle type) allowing higher fluid flow.Its compact design incorporates the following advantages:To allow an integral and compact installation, in place of numerous valves and fittings usually required for a conventional systempreparation, minimizing the potencial leakage points.ISOLATIONVALVEISOLATIONVALVEVD-FLUXCOMPOSEDSTEAMTRAPBLOWDOWNVALVETESTVALVECONDENSATERETURNTYPICAL STEAM TRAP INSTALLATIONPROPOSED ASSEMBLINGThe Piston Type Universal Flow Distribution Valve (VD-Flux) has a 3-year guarantee.01
