Pneumatic Dispensing Valve MY-3131, Back-Suction Precision, Nut Mouth

The MY-3131 is a pneumatic needle-type dispensing valve with back-suction (vacuum retraction) for ultra-clean cut-off of dots and beads. Its nut-type outlet securely clamps standard dispensing needles/nozzles and keeps flow stable for CA, epoxy, UV adhesives, flux, oils, and other process fluids.

Key Features

• Back-suction / anti-drip: Instant retraction at shot end prevents oozing, stringing, and tailing.

• Fine stroke/flow adjuster: Tune deposit size from micro-dots to continuous beads with repeatable results.

• Nut-type nozzle mount: Threaded “nut mouth” nose holds standard tips firmly (common 1/4-28 style / Luer-type adapters).

• Rigid, cleanable build: Stainless wetted path with anodized aluminum body for durability and chemical resistance.

• Easy integration: Push-in air fittings and fluid inlet; runs from a benchtop time-pressure controller and foot pedal/PLC.

• Wide fluid compatibility: Works with low- to medium-viscosity adhesives, sealants, inks, oils, and flux (check compatibility).
