Ultra-Fast, Ultra-Low Power Draw Piezo Actuated Valves

With Marotta’s advanced technology you can control flow parameters in real time and adjust orifice size to meet your desired flow and pressure. The responsive actuator, integrated pressure transducers and strain gauges allow Marotta to deliver state-of-the-art proportional control in a compact and lightweight package. The valve has the capability to measure the inlet pressure as well as the orifice size at any instant.

  • Up to 10,000 psi
  • Multi-functional operation: isolation and regulation
  • < 0.5 millisecond operation
  • < 1 milliamp power draw
  • Proportional control

In-Line Valves Optimize Performance to Size Ratio

This unique multi-function high flow technology features a distinctive coaxial flow path that offers a significantly lower pressure drop compared to conventional valves of similar size.Can be used as either a check valve, shut off valve, reducing valve or relief valve.

  • Space saving axial flow configuration
  • Reduces manpower requirements
  • Piloted or motor operated
  • Simple, rugged and reliable

Manifolds – Compact, Reliable, Easy to Maintain

We integrate the functionality of a wide range of components into a single manifold, providing the flexibility to match products to specific requirements for efficiency and ease of maintenance. Our offerings range from simple single inlet to multiple outlets, to multi-chambered flow control units. Our manifolds are of single block or “building block” construction, and all valving is plug-in type.

  • Improve performance
  • Save space
  • Decrease costs

Single Stage Pressure Reducers

Available as lightweight stand-alone valves or as cartridge designs, our single stage pressure reducers cove a wide range of regulated outlet pressures. Marotta regulators offer an integral relief valve to accurately maintain system pressure without the need for an additional relief valve. Stand alone and cartridge designs, spring and dome references, and pneumatically controlled (piloted). Metallic pistons maintain constant sensing area and eliminate “diaphragm fatigue”.

  • Protect against over-pressure
  • Wide range of flows and pressures
  • Eliminate “diaphragm fatigue” failures
