Dispensing Valves

By determining your desired fluid viscosity, fluid content, and application type, Fisnar can identify the best dispensing valve for the job. We offer spool valves for high viscosity materials, poppet valves for smaller shots sizes, diaphragm valves for volatile fluids and UV resins, pinch-tube valves for volatiles and cyanoacrylates, needle valves for dots, and auger valves are for high viscosity fluids such as solder paste applications.

 

Diaphragm Valve

Diaphragm Valves

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.

Dispensing Valve Controllers

Dispensing Valve Controllers

Fisnar dispensing valves all require the aid of a valve controller. Most valves require a timed shot of compressed air that will open and close the valve, while some valves require a controller that will actuate the motor in the valve.

Needle Dispensing Valves

Needle Dispensing Valves

Lightweight needle valves are designed for hand-held dispensing of micro-shots and small beads of medium viscosity materials. They are available with stainless steel wetted chambers, plastic or aluminum chambers.

Pinch Tube Valve

Pinch Tube Valves

Pinch tube valves are often used for volatile fluids, such as in cyanoacrylate and solvent dispensing. Because the wetted parts are replaceable at a low cost, the valve can also be used with two-part resins and placed at the end of a static mixing nozzle.

Poppet Valves

Poppet Dispensing Valves

Poppet valves are multipurpose valves used for small shots and bead dispensing of medium or high viscosity fluids. They can dispense up to 300 times per minute and have a suck-back feature to prevent post-dispense dripping.

Positive Displacement Valves

Positive Displacement Dispensing Valves

Positive displacement valves are available as either servo-driven auger valves or peristaltic dispensing pumps. Auger valves are suitable for dispensing high viscosity pastes, while peristaltic dispensing pumps use a volumetric valve.

Rotary Valve

Rotary Valves

Rotary valves are 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 material at the end of bead path.

Spool Valve

Spool Dispensing Valves

Fisnar’s spool action valves are a balanced type “on/off” segmented valve. Applying pressure to the air inlet forces the spool forward, dispensing the material. Releasing the air pressure results in the internal spring snapping back into position and closing the valve.

Spray Valves

Spray Dispensing Valves

Spray valves are designed for dispensing urethane, paint, flux, and lubricants for conformal coating applications. All spray valves are made of stainless steel and provide close tolerance spray dispensing and are engineered to prevent material clogging.
