Short-Stem PU Foam Valve for Controlled Straw Dispensing

Short-Stem PU Foam Valve for Controlled Straw Dispensing

Product Description

This PU foam aerosol valve is a heavy-duty dispensing system engineered for use with pressurized polyurethane foam cans. Designed to handle high-viscosity and chemically reactive formulations, the valve ensures smooth and controlled foam discharge that expands upon contact with air.

Built to withstand elevated internal pressure, the valve features a short-stem, clog-resistant design that prevents pre-cured foam from hardening inside the mechanism. This guarantees reliable sealing, consistent flow, and extended service life. The precision-engineered structure supports clean foam cut-off after application, making it suitable for both professional construction environments and DIY home use.

Key Features

• High-pressure rated construction for PU foam systems
• Clog-resistant nozzle with clean-cut dispensing mechanism
• Chemical-resistant materials compatible with polyurethane formulations
• Consistent flow control for uniform foam application
• Durable actuator designed for repeated professional use

Application Scenarios

• Filling gaps, joints, and cracks in construction projects
• Installing insulation around windows, doors, and piping
• Sealing, soundproofing, and thermal insulation applications
• DIY home repair, renovation, and crafting projects

Frequently Asked Questions (FAQs)

Q1: What types of PU foam formulations is this valve designed for?
A: This valve is engineered for one-component polyurethane (PU) foam systems, including standard expanding foams, low-expansion foams, insulation foams, and soundproofing formulations.

Q2: How does the valve prevent clogging during use and storage?
A: The valve incorporates a short-stem, clean-cut mechanism and chemically resistant internal materials that prevent pre-cured foam from hardening inside the valve after dispensing.

Q3: Is the valve suitable for high-pressure PU foam cans?
A: Yes. The valve features a high-pressure rated construction designed to safely withstand the internal pressures generated by pressurized polyurethane foam systems.

Q4: Can this valve be used with straw-type applicators?
A: Yes. The short-stem design is specifically optimized for straw application, allowing precise foam placement in narrow gaps, joints, and hard-to-reach areas.

Q5: Is the valve compatible with professional and DIY applications?
A: Absolutely. The valve is built to meet professional construction standards while remaining easy to use for DIY home repair and renovation projects.

Future industry manufacturing complex spans an area of nearly 7,000 square meters. It incorporates six high-speed aerosol valve production lines and more than 30 special valve production lines.

Each year, Future industry aerosol can produce up to one billion aerosol valves. Our main products are air freshener aerosol valve, insecticide spray aerosol valve, butane gas aerosol valve, carburetor cleaner aerosol valve, ribbon spray aerosol valve, snow spray aerosol valve,paint spray aerosol valve, fluid spray aerosol valve, portable stove gas aerosol valve, 360 degree aerosol valve, powder spray aerosol vave. Also we have expanded the export market of aerosol metering valves, aerosol caps and aerosol cans.We have also built five standardized workshops to conduct different operations in order to meet the requirements of various customers to ensure we always meet production demands and timelines.

Production of the valve mounting cups is carried out in this workshop. We use a high-speed automatic stamping machine to transform high-quality steel plates into valve mounting cups. Due to the high degree of its automation, this equipment can help to reduce labor costs and increase production efficiency significantly.

In addition, we utilize an efficient machine that can automatically press an outer rubber ring into a valve mounting cup in order to provide superior sealing performance in the process of final assembly.

This workshop contains over 20 injection molding machines and three injection molding lines. Among them, our injection molding machines are used to produce a variety of accessories such as valve stems, valve chambers, actuators, and spray caps, etc.

Due to efficient automation, we require a very small number of staff to run these more than 20 injection molders. During the production process, our quality control inspectors are responsible for sampling and testing every batch of accessories. Additionally, our injection molding line has the capability to produce various sizes of dip tubes in automatic mode.

This workshop is used to assemble all kinds of accessories. It is equipped with automated assembly equipment to greatly increase production efficiency and provide our customers with enhanced profits.

After assembly is completed, our valves will be automatically counted and packed. We are proud to say we are one of the few companies in the industry that possess advanced abilities in product research and development. Every new product needs an innovative mold. For this reason we utilize high-precision wire cutting machines and machine tools that can form our molds into exquisite shapes.

We possess a wide range of technical production and R & D expertise

Whatever your industry related need may be, just ask, we can provide the solution.
