HDA Regulating Valve with Air Pilot
Brand: Watson McDanielThe HD Regulator with the "A" Air Pilot is used for reducing steam pressure on steam mains and process equipment. The "A" Air Pilot can also be used in conjunction with the PTL and PTR Pneumatic Temperature Controllers for controlling temperature in process applications.
The principal advantage of the "A" Air Pilot over standard spring-loaded pilots is that pressure adjustments to the regulator can be made from a remote location. A regulator placed in a difficult to reach or inaccessible location can be adjusted by a remote control panel board placed in an accessible location.
Features- Air Pilot can be used with PTL or PTR Pneumatic Temperature Controller
- Pressure adjustments of the regulator can be done from a remote location
- Air-operated pilot insures instant response and very accurate control
- Full port strainer and blowdown valve on pilot adapter for ultimate protection from dirt and scale
