Pressure Regulators/Reducers

Pressure Regulators/Reducers

Stand Alone and Cartridge Designs

Marotta’s pressure regulators / reducers provide precise adjustment across a wide range of flows and pressures.  Stand alone and cartridge designs, spring and dome references, and pneumatically controlled (piloted).

Ideal for applications using Freshwater, Helium, Nitrogen, Xenon, CO2, Argon, Oxygen, GHe, GOX and more.  

Electronic Regulation

Marotta Controls’ innovative electronic regulator is a hybrid mechanical-electronic system capable of flexible, accurate and stable pressure regulation across a large pressure ratio.  With a closed loop electronic control system controlling the piezo-actuated pilot valves, the regulator constantly measures actual downstream outlet pressure and adjusts to changing inlet conditions, resulting in an accurate outlet pressure insensitive to inlet pressure, flow rate and temperature. 

Features:
  • Up to 10,000 psi
  • Low weight
  • Minimal power consumption
  • Fast response
  • Proportional valve response

Pressure Regulators

The pressure regulators, in addition to the above, offer an integral relief valve.  This arrangement provides assurance against over pressure which may result from thermal effects or accidental seat damage.

Our pressure regulators offer an integral relief valve accurately maintain system pressure without the need for an additional relief valve.

Features:
  • Balanced poppet design
  • Stainless steel or brass body standard, other materials available
  • Standard seal materials Buna-N, Fluorocarbon, Teflon, etc.
  • Customized Solutions are available
  • Inlet pressure ranges up to 15,000 psig
  • Up to 8″ IPS – other line sizes available on request

Hand Regulators are also available – Spring or dome loaded regulators for high pressure air systems.

Pressure Reducers

Lightweight, dual capacity with a wide range of regulated outlet pressures.  Our pressure reducers, commonly used in conjunction with pressure relief valves to control system pressure, feature the Marotta-originated balanced poppet and a metallic sensing poppet.  This design virtually nullifies all pressure forces acting on the poppet, therefore even widely varying inlet pressures have little effect on the regulated pressure.

Metallic pistons maintain constant sensing area and eliminate “diaphragm fatigue” failures.  Several piston sizes are available for selection depending upon outlet pressure range and accuracy desired.
