Manufacturing and assembling products in a cleanroom environment require specialized equipment to
reach specific ISO cleanroom standards. One common tool used in cleanroom manufacturing and
assembly is the nitrogen spray gun. iPolymer is a dedicated global manufacturer of high-purity fluid
handling products and cleanroom manufacturing equipment. We offer 3 different nozzle configurations:
Nitro-1, Nitro-2, and Nitro-2-FT which are the standard hand spray, standard spray gun, and front trigger
spray gun respectively.  In combination with various hose material and fittings, we offer 6 different
packages: the Nitro-3, Nitro-3T, Nitro-4, Nitro-4T, Nitro-4-FT, and Nitro-4T-FT.

Nitrogen spray guns are a specialized cleaning tool designed to effectively clean large surfaces in
cleanroom manufacturing and assembly applications. Molecular Nitrogen () is a common diatomic
molecule composing of 78% of the Earth’s atmosphere. Two nitrogen atoms form a triple bond resulting
in a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures. Nitrogen gas is
cleaner and drier than conventional air, making it effective for clearing microscopic debris from surfaces.
PTFE is a synthetic fluoropolymer of tetrafluoroethylene consisting of long chains of carbon and fluorine
atoms which results in chemical inertness. Polypropylene is similarly a thermoplastic polymer consisting
of long chains of carbon and hydrogen atoms which also results in high chemical resistance. Our spray
guns are primarily composed of PTFE and Polypropylene and are designed for peak protection against
corrosion, acid deterioration, and acid fume attacks.

The most common products you will see produced with nitrogen spray guns include semiconductors,
medical devices, optical lenses, military, and aerospace equipment, food packaging, and various small
electronics. Manufacturers will most often require nitrogen spray guns to keep surfaces clean that
cannot otherwise be touched or exposed to liquids and/or metals. These tools are typically mounted to
wet benches and work process stations.

Customers typically can find the right nitrogen spray gun for their needs within our selection of stock
models. We also, however, offer highly customizable design services, to prototype and produce a unique
nitrogen spray gun for your specific application.

Our nitrogen guns have a max operating pressure of 75PSI with a media temperature range of 40°F to
130°F.

PTFE is a widely utilized material in high purity fluid handling applications, such as chemical processing and gas analytics. iPolymer solenoid valves feature a wetted PTFE surface that offers chemical resistance and easy cleaning between process runs. At iPolymer, we offer two main categories of PTFE solenoid valves: Miniature and Subminiature. Both are available with multiple body configurations, seat sealing methods, and solenoid coils. We offer our PTFE solenoid valves in 2-way normally closed, 2-way normally open, and 3-way configurations. Compare the key benefits and differences between our miniature and subminiature valves below.

 

Miniature PTFE Solenoid Valves

Our iPolymer Miniature Solenoid Valves use an all PTFE wetted flow path design that is optimized for ultra-clean, semiconductor, pharmaceutical, biomedical, and chemical processing applications. These valves will work well in extreme conditions, including vacuum applications and unique manifold configurations. We strive to make our valves as versatile as possible, with the option to configure an EPDM, Viton, Aflas, Kalrez O-Ring, or PTFE Hard Seat. Because of our great configurability, iPolymer Miniature PTFE Solenoid Valves can work with a wide array of media. Other key advantages of these valves include:

• Diaphragm configured to completely isolate solenoid coil from media
• Proven technology that maximizes the speed, accuracy, and repeatability of coil response time
• Valve seat design for tight shut-off and positive flushing
• Ability to handle aggressive media, vacuum applications, and elevated temperatures
• Available as a 2-way or 3-way valve, with multiple body configurations

 

Subminiature PTFE Solenoid Valves

iPolymer Subminiature Solenoid Valves are also designed to perform under extreme conditions, with exceptional resistance to chemicals, temperature, and corrosion. An all-wetted PTFE surface design ensures these valves can be used in high-purity and sanitary applications, such as chemical and bio-medical production. Our standard Subminiature Solenoid valve is configured with PTFE surfaces for the body, stem, and diaphragm.  Like our Miniature models, our Subminiature Solenoid Valves offer the same O-ring seat seal options, including EPDM, Viton, Aflas, and Kalrez. Some key highlights of these valves include:

 

• Ability to configure for AC and DC voltages
• Quick, accurate, and consistent coil technology

Chemical processing equipment is an essential part of producing critical media for several industries.  Foods, beverages, oil and gas, chemicals, and even water are all processed through comprehensive chemical processing systems, using an array of advanced equipment. One of the most common pieces of equipment is the pneumatically actuated ball valve. At iPolymer, we specialize in delivering the very best fluid handling chemical process equipment to our customers across a wide range of industries. Narrow down your search further by referencing this quick guide on key types of pneumatically actuated ball valves.

                      

Materials of Construction: Teflon (“PTFE”)

 

Compared to brass and stainless steel, Teflon (“PTFE”) Pneumatically Actuated Ball Valves are designed to handle extremely corrosive media.  The materials of construction for the wetted flow path are exclusively manufactured from high-quality pure Polytetrafluoroethylene (PTFE). The PTFE Body, Ball, Stem, and Ports of the Valve ensure both corrosion resistance and minimal leachable exposure. High purity media for critical applications in semiconductor and pharmaceutical production cannot be exposed to brass or stainless steel.  The PTFE Pneumatically Actuated Ball Valve offers an inert flow path that protests the media.

 

Two-Piece Construction

 

The most common type of construction for a PTFE Pneumatically Actuated Ball Valve is a two-piece design.  A PTFE ball is placed within a PTFE body.  Adding end ports and a stem completes the critical design components.  A pneumatic actuator is added at the top of the valve, mounting to the stem and supported by the body.

 

These valves are easily maintained and can operate for several years maintenance-free.  The Teflon on Teflon running surfaces ensure a low maintenance long life.

 

Actuator and Source Pressure

 

Pneumatically Actuated Ball Valves require a source control pressure to actuate the valve.  While this is typically clean dry air (CDA), some applications call for Nitrogen (N2) gas.  The actuation pressure drives the actuator mounted on top of the ball valve.  These actuators can be configured for Air to Open and Spring to Closed, or Air to Open and Air to Close, or Spring to Open and Air to Close.  The actuators can include end-of-travel limit switches and positive position indication.  The most common Pneumatically Actuated Ball Valve is a quarter-turn (90-degree rotation) valve.  The ball within the valve body is rotated by the stem and actuator 90 degrees from an open to closed position.

 

Alternate Body Configurations

 

While the PTFE Ball Valve is our most common configuration.  Ball Valve bodies and stems can be manufactured from Polypropylene, PVC, and UHMW.  Frequently the internal ball will remain manufactured from PTFE material.  Some designs are configured with O-Ring seals, while others use a Double Split-V Ferrule configuration to seal the media from the outside world.

 

Semiconductor Wafer Processing Tools

 

Common applications for Pneumatically Actuated PTFE Ball Valves include main shutoff and blocking valves for harsh chemistry and DI water in Semiconductor Wafer Processing Tools.

 

Wafer Processing equipment frequently will daisy chain two, three, or four banks of tools together and use PTFE Ball Valves to feed chemistry from a common holding vessel to the tools.  PTFE Ball Valves act as excellent blocking valves and main shutoff valves.
