Valves

The LS System enhanced pneumatic valves are designed for higher operating pressures than the standard line and continuous use at high actuation frequencies such as for precision pressure control.

The M series pneumatic valves are instrument-grade, proportional, directional control pneumatic valves for high performance applications such as medical equipment, test and measurement systems, advanced automation and animatronics.

Product Lineup

PFV 2/2 Proportional Solenoid Valves

PFV liquid and gas 2/2 proportional solenoid valves simplify design and construction of medical, life-science, semiconductor and other OEM equipment. PFV valves feature a wetted path made of 300 and 400 series stainless steel and FKM, FKM (NSF Certified), EPDM and FFKM seal options.
PFV proportional solenoid valves flow not only air and water but also the most challenging media. Available in six available orifice sizes ranging from Ø0.5 mm (0 to 130 mLPM liquid and 0 to 4.3 SLPM gas) to Ø1.75 mm (0 to 2.5 LPM liquid and 0 to 140 SLPM gas).

RCV 2/2 Servo Proportional Valves

The RCV valve is a low pressure (under 2 psig), high flow (100s of LPM) servo proportional valve that enables precision flow control applications by providing poppet positioning to within ±0.5% of full travel.
Available in either analog (0…5Vdc or 0…10Vdc) or SPI communications that enable fast, accurate commands and status updates between the valve and microprocessor.

VQV Pressure‐Compensated Proportional Valves

The VQV series of high‐flow pressure‐compensated proportional valves for air, oxygen and other neutral gases work across a wide range of pressures (0…7 bar) and flows (0…324 slpm) due to their innovative design.
This design minimizes the effect of inlet pressure on valve opening, making them ideal for medical, life science and advanced automation applications requiring high flow rates in a small footprint with minimal power consumption.

ECS 5/3 Servo Proportional Directional Valves

The ECS 5 port 3 position (5/3) servo proportional directional valve is the ultimate for both open and closed-loop pressure, flow, position and force systems.

A high force, high speed, high efficiency voice coil actuator opens the valve to any flow rate within milliseconds with an average power consumption of less than 0.5W (10x less than similar valves).

ELB 5/3 Proportional Directional Valves

The ELB Series 5/3 high speed proportional directional valves are manifold mount pneumatic valves capable of the wide pressure range of full vacuum through 300 psig. Internally pressure balanced, inlet pressure has no affect on when these valves begin to open.

Driven by a high-speed linear force motor, the ELB series of valves have a shifting time of less than 2.5ms. Able to open to any amount quickly, these valves are used in both closed loop and open loop pressure, force, position and flow control applications.

Enfinity® Series 5/3 Proportional Directional Valves

The Enfinity® Series 5/3 high speed proportional directional valves are instrument grade, pneumatic control valves engineered for high performance flow, pressure, position and force applications.

In addition to the proportional response and ultra-fast response time, the construction of these valves feature an IP65 environmental protection rating and 3/8” NPTF ports, for the highest flow capacity of the entire product line.

LS 5/3 Proportional Directional Valves

The LS Series 5/3 high speed proportional directional valves are the ultimate in proportional control for both closed loop and open loop pneumatic systems. With shifting times less than 2.5 ms and linear proportionality, they surpass even high performance solenoids, allowing designers to create breakthrough applications.
With three different valve sizes, the LS Series can cover a wide range of applications with unprecedented valve aperture control.

ENV 2/2 Motorized Needle Valves

The ENV series of motorized needle valves for proportional flow rate adjustment combine the accuracy and repeatability benefits of a stepper motor with the linearity and resolution of a needle valve.

The result is adjustable flow control with less than 2% hysteresis, 0.1% repeatability and 0.2% resolution – making these valves ideal for consistent, high-performance delivery of gases and liquids in medical, life science and advanced-automation applications.

EQV Proportional Pinch Valves

The EQV series of proportional pinch valves controls the flow rate of a liquid or gas passing through a tube by squeezing from the outside, providing complete media isolation. This makes the EQV series ideal for control of hygienic, high-purity, sanitary, and corrosive liquids and gases.

To squeeze and relax the tubing, a high force stepper motor, actuates in both directions providing repeatable, consistent flow – ideal for pharmaceutical, bio-tech, semiconductor, life science, and food & dairy applications.
