Type EZR Pressure Reducing Regulator - Emerson Electric
www.emerson.comThe Type EZR pilot-operated, pressure reducing regulators are used for natural gas, air or other non-corrosive gas applications and include a Type 112 restrictor and a 161EB, 161AY or PRX Series pilot. Pilot Type Descriptions Type 161AY—Low-pressure pilot with an outlet pressure range of 6 in. w.c. to 7 psig / 15 mbar to 0.48 bar.
FUNDAMENTAL PRINCIPLES OF PRESSURE REGULATORS
asgmt.comJan 07, 2003 · the three sub-categories of Constant-Loaded, Pilot Operated, and Pilot Unloaded. Make no mistake; these three design are vastly different and, thus, will exhibit significantly different performance characteristics. Each of these designs is covered in more detail later in the paper. REGULATOR DEFINITION A pressure regulator is a feedback control ...

Water Pressure Reducing Valves
media.wattswater.comThere are two types of water pressure reducing valves: pilot-operated and direct-acting. Types of WPRVs Pilot-operated valves have a sensing control pilot and main valve in one unit. These valves are typically used in commercial appli-cations such as schools, hotels and hospitals, as well as in industrial and municipal applica-tions and installa-
GAS PRESSURE REGULATORS CATALOG
www.maxitrol.comWhen sizing a regulator the following must be known: • Gas Type • Available Inlet Pressure • Desired Outlet Pressure • Zero Governor Application (indicated by model number ending in “Z”) • Will the regulator control main burner and pilot load OR main burner only? • 3Required minimum and maximum flow rate in cfh or m/h or Btu/h

wwwd.graco.coma. Install an air regulator (C) and gauge to control the fluid pressure. The fluid outlet pressure will be the same as the setting of the air regulator. b. Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. See the WARNING above. Locate the other master air valve (E) upstream from all air
VR8200; VR4200 Combination Gas Controls
customer.honeywell.comThe VR8200 Continuous Pilot Dual Automatic Valve Combination Gas Controls are used in gas-fired, standing pilot appliances. They include safety shutoff, a manual valve, two automatic operators, a pressure regulator, a pilot adjustment, and a conduit cover (VR4200 only). VR8200 for use with 24 Vac heating appliances and
Pressure boosters DPA - Festo
www.festo.comsure is set using a manually operated pressure regulator. In the case of pressure boosters without a pressure regulator, the output pressure is always twice the supply pressure. The air supply to both drive pistons is controlled by a pneumatic directional control valve that reverses automatically when the stroke end position is reached.
Cross Reference - Emerson Electric
climate.emerson.comGas flow to the pilot burner is controlled by a safety valve which is manually operated and held in by current generated from a thermocouple placed in the pilot flame. When the thermostat calls for heat the main valve is energized. Proven Pilot The thermostat calls for heat and simultaneously energizes the pilot valve and the Proven Pilot control.
