Multi-Function Proportional Control

Multi-Function Proportional Control

Isolate. Regulate. Modulate.


The special multi-function characteristics of this valve family means that JUST ONE VALVE can be used for isolation and regulation – which with conventional valves would require several different devices.

With Marotta’s advanced electric valve technology you can control flow parameters in real time and adjust the orifice size to meet your desired flow and pressure. The responsive actuator and integrated pressure transducers allows Marotta to deliver state-of-the-art proportional control in a compact and lightweight package.


 

  • Sizes from 1/8″ to 4″
  • High dynamic control
  • Power consumption: 
  • Lightweight, compact design
  • Pressures up to 10,000 psig
  • Response time
  • Flow rate: 0.02 mg/sec (Xenon) up to 2000 GPM (water)
  • Control voltage as required

Choose from a wide selection of sizes and control methods:
 
Miniature, Internally Piloted

Normally closed miniature valves have demonstrated internal leakage rates less than 1×10-5 sccs of GHe at temperatures from -54°C to 93°C and precise, modulating pressure/flow regulation up to 3000 psig. Ideal for satellite applications.

 
Mid-Size, Super Fast with Pressures up to 10,000 psig

Sub-millisecond response, compact and lightweight mid-size proportionally controlled valve. On/off operation at continuous duty, handles pressures up to 10,000 psig with minimal heat generation.

 
High Flow Rate in a Compact, Self-Contained Control Valve

Motorized, direct acting low profile in-line valve series does not require line pressure or another source to operate the valve, making it ideal for high flow applications
