Our medium pressure rated, stainless steel needle valves exceed the 20,000 psi industry standard and can be used with either gases or liquids.

Maximator® needle valves are high quality with a high level of safety and reliability under adverse operating conditions. Traceability is ensured through extensively documented data, including batch number, maximum pressure, material number and type designation.

We offer a large selection of 2-way and 3-way needle valves available with 1/4, 3/8, 9/16, 3/4, 1", 1.5" O.D. and 4MF, 6MF, 9MF, 12MF, 16MF, 24MF medium pressure connection types. Select one of the options listed below for information on specific needle valve styles. All medium pressure valves include glands and collars.

MAXPRO® also offers a complete line of medium pressure components, including ultra and high pressure needle valves.

We offer specialty packing for valves that must operate in extreme temperatures from -423 ºF to 1200 ºF. Please consult a MAXPRO® representative about this type of specialty design.

Maximator® Double Block and Bleed Needle valves with full bore will allow you to control the entire flow of your application combined with the proven benefits of an Integrated solution.

Maximator® series DBBNV Double Block and Bleed Needle Valves with metal to metal seats have a high level of safety and reliability under adverse operating conditions. Double Block and Bleed Needle Valves are three stem manifold valves designed for blocking and bleeding in test and pressure monitoring applications as well as for chemical injection or drain line isolation up to 22,500 psi (1,550 bar).

Due to the standard valve packing and Vee stem design, Maximator® double block and bleed needle valves are very compact and easy to use. In addition, manifold style valves reduce the number of fittings and space required for installation.

At Maxpro Technologies, we carry a full line of quality Maximator Air Actuated Valves for Hydrogen Service.  These valves are a great option for slow fill processes in compact filling stations up to high flow rates for hydrogen fueling stations for buses, trucks, and trains.

Exceeds industry standard of 20,000 psi. MAXPRO® offers a complete line of Maximator® medium pressure fittings, tubing, check valves, line filters, anti-vibration fittings and safety head assemblies.

Maximator® medium pressure fittings are designed with the large orifice for use with the 21V series medium pressure valves and medium pressure tubing. All medium pressure fittings have coned and threaded type connections. Mounting holes are standard on all elbows, tees, and crosses.

Connection Components
All medium pressure fittings are supplied with glands and collars. Refer to the adjacent chart for ordering any of the connection components individually. When using the plug, the collar is not needed.

Exceeds industry standard of 20,000 psi. MAXPRO® offers a complete line of Maximator® medium pressure fittings, tubing, check valves, line filters, anti-vibration fittings and safety head assemblies.

Exceeds industry standards of 15,000 and 20,000. MAXPRO® offers a line of coned and threaded medium pressure tube nipples in a variety of lengths for all standard tube sizes.

The coned and threaded medium pressure tube nipples are available in 316 stainless steel. Special length coned and threaded nipples are available upon request.

Maximator® ball check valves prevent reverse flow where bubble tight shutoff is not mandatory. These check valves are designed with a ball cradled floating poppet to assure positive inline seating. This poppet design allows full flow around the ball to minimize pressure drop. Check valves are rated to 660ºF. All check valves are supplied with glands and collars. These check valves are not to be used as a relief device.

Materials.
Body, cover, poppet, cover gland: 316 series stainless steel
Ball and spring: 300 series stainless steel.

Especially for hydrogen applications, where best of class sealing ability is required, Maximator® developed their cone check valve series design with a highly media compatible soft sealing system and improved spring guide. This series is available for Medium Pressure applications up to 22,500 psi (1.550 bar) with 4M to 16M connection.

Exceeds industry standard of 20,000 psi. Maximator® cup-type line filters are used when maximum filtration surface area and a single micron size element is preferred. This design increases the filter area as much as 6 times the area of the disc type filter, and will permit higher flow rates with a lower pressure drop, and longer intervals between element changes. Filter elements come standard in 5, 30, or 56 micron sizes and are easily replaced. Filters are rated for temperatures -60ºF to 660ºF. All line filters come with glands and collars.

Exceeds industry standards of 20,000 psi. Maximator® safety head assemblies are used to provide over-pressure protection to high pressure systems. These safety head assemblies are to be used with the appropriate 1/4" angular rupture disc.

1/4" angular rupture discs are designed to be used with Maximator® safety head assemblies. Minimum rupture disc pressure ratings should be at least 110% of system operating pressure. The standard material is 316L SST. The pressure ranges indicated in the table below are at room temperature (72ºF).

MAXPRO® offers a line of cold drawn thick wall tubing, with flow areas to compliment the large orifice medium pressure valves and fittings. This tubing is made under strict manufacturing and quality control standards and inspections, with dimensional tolerances to match the requirements of the medium pressure coned and threaded connections.
MAXPRO® offers a complete line of Maximator® medium pressure fittings, tubing, check valves, line filters, anti-vibration fittings and safety head assemblies.

MAXPRO® offers a complete line of coning and threading tool kits for manually coning and threading 1/4" O.D. to 9/16" O.D. tubing.
There are three different tool kit versions, the "Medium" pressure, "High" pressure, and the "Complete Kit" that contains both the Medium and the High Pressure tools. All kits are conveniently packaged in a sturdy hand carry tool case with removable top tray. The unique coning and threading tool designs allows for interchange ability between components, eliminating multiple tool inventories.
