Avoid deposits
May 1st 2006

Avoid deposits Parker Instrumentation has developed a novel new rising-plug style valve for process instrumentation applications. A patented design provides users with a reliable valve solution for applications where contaminated media can lead to premature valve failure. Called the HRPV Series, the rising plug valve's 'straight-through' design supports higher flow rates than needle valves, helping to avoid the build-up of deposits. It additionally allows cleaning to take place by rodding.

The HRPV Series valve features an 8-turn actuation cycle, with a rolled spindle thread and smaller sealing area - lowering the torque required when controlling high pressure fluid flows and providing a long life. Despite the valve's very high pressure capability - it's rated to 10 000 PSI (689 bar) - a typical actuation torque of just 25 poundinches (2.82 Nm) of torque is required.

The HRPV valve has a 1/4 inch (6.4mm) orifice with a Cv of 1.8, but can be supplied with either 1/4 or 1/2 inch ports, with a range of end connections including male and female NPT, and twin-ferrule ALOK compression tube fittings.
