Dispensing Valves

Diaphragm Valve

Diaphragm valves provide precision micro-shot dispensing of liquids such as cyanoacrylates, solvents, electrolytes, alcohols, and acids. A single part diaphragm and seal separates the wetted parts for reduced maintenance. Diaphragm valves for UV cure and anaerobic materials are also available.

Needle Valves

A lightweight needle valve designed for hand-held dispensing of micro-shots and small beads of medium viscosity materials. The valve is available with stainless steel wetted chambers for UV cure dispensing, plastic chambers for anaerobic dispensing, or aluminum for dispensing silicones, grease and lubricants.

Pinch Tube Valve

A pinch tube valve can be used in many situations, it is regularly used for volatile fluids, such as in cyanoacrylate and solvent dispensing. The advantage of this valve is that the wetted parts are replaceable at a low cost. Because of this, the valve can also be used with two-part resins and placed at the end of a static mixing nozzle.

Poppet Valves

Poppet valves are multipurpose valves suitable for small shots and bead dispensing of medium or high viscosity fluids such as silicones, grease and paste. Poppet valves can dispense up to 300 times per minute and are developed with a suck-back feature to prevent post-dispense dripping.

Positive Displacement

Positive displacement valves are available as either servo driven auger valves or peristaltic dispensing pumps. An auger valve is a servo motor driven valve suitable for dispensing high viscosity pastes. A peristaltic dispensing pump is a volumetric valve with an adjustable chamber for accurate deposits.

Rotary Valves

Designed to deliver a uniform bead dimension irrespective of any air pressure build-up at the opening of the valve and at the start of the bead. This neutralizing pressure feature ensures a perfect bead with a clean cut-off of the material at the end of the bead path.

Spool Valve

Fisnar's spool action valves are a balanced type "on/off" segmented valve. Applying pressure to the air inlet will force the spool forward, under tension from an internal return spring, dispensing the material. Releasing the air pressure results in the internal spring snapping back into position and closing the valve.

Spray Valves

Fisnar Inc. Spray Valves are designed for dispensing urethane, paint, flux, and lubricants and for conformal coating applications. All spray valves are made of stainless steel and provide close tolerance spray dispensing. The spray nozzles are specially engineered to prevent material clogging and a stroke adjustment provides accurate

Controllers

Fisnar dispensing valves all require the aid of a valve actuation controller.  the majority of our valves require a timed shot of compressed air that will open and close the valve. While some of our other valves require a controller that will actuate the motor in the valve.
