ROSS Pneumatic Valve Full Series

Function: Gradually establish downstream pressure to prevent sudden equipment action during startup.

Structure: 2/2 or 3/2 normally closed, with adjustable needle valve, fully open when downstream pressure reaches about 50% of intake pressure.

Interface: 1/4 "to 1 1/2", Cv 1.2~30。

Integration options: Can be combined with L-O-X (blue handle, partially open first and then fully open).

3. Control Reliable Double Valves

The highest safety level valve used for energy isolation and press clutch/brake control.

DM1 series E (dynamic monitoring, no memory)

3/2 normally closed, two valve cores are monitored synchronously. If asynchronous action occurs, the outlet is cut off (residual pressure<1%).

Automatically reset after fault clearance (no latch memory).

Interface: 1/4 "and 3/8", Cv 1.3~2.2。

Certification: Compliant with ISO 13849-1 Class 4 PL e.

DM2 ®  Series E (Dynamic Monitoring+Memory)

Add a latch function on the basis of DM1, and after a fault, it must be manually reset through a reset solenoid valve or remote gas signal.

The same applies to 3/2 normally closed, 1/4 "and 3/8", Cv 1.3~2.2。

Reset method: Built in solenoid valve (24 V DC or 110/120 V AC).

DM2 ®  Series C (suitable for high traffic)

Sizes 4, 8, 12, and 30 correspond to 1/2 "to 2" interfaces.

Cv：4.4~22， Weight 5.9~34.7 lb.

Integrated status indicator pressure switch (NO/NC contact).

Reset can be achieved through remote gas signals, solenoid valves, or manual buttons.

DM2 ®  Series D (dedicated to press clutch/brake)

Compliant with OSHA 1910.217 and ANSI B11.2 standards.

Built in total dynamic monitoring and complete memory, it must be automatically reset after a fault occurs.

Basic dimensions 2, 4, 8, 12, 30, Cv 2.17~20.22。

Optional remote gas reset, electromagnetic reset, or manual reset.

The export response time can be calculated using the formula t=M+F × V (where M is the mechanical constant and F is the milliseconds per cubic inch).

4. Pilot operated one-way valve (19, 27, SV27 series)

Function: Load retention to prevent the cylinder from accidentally falling.

Type: 2/2 normally closed, pilot pressure open, one-way cutoff without pilot.

Integrated pressure relief function: optional remote pneumatic pressure relief, manual pressure relief, or electromagnetic pressure relief.

The SV27 series integrates a double pole single throw switch (DPST) that provides position feedback and can be used for safety circuits (Cat.2 PL d).

5. CrossMirror ®  Double valve (77 series and CM series)

Used to reliably return the cylinder to its original position (such as press protection).

77 series: 5/2 dual valves, built-in dynamic monitoring, output port 2 (return) maintains pressure in case of failure.

CM series: Modular design, can be combined into multiple valve groups, with status indication and reset function.

6. Explosion proof valves (27 series and 21 series)

Certification: CSA/FM Class I Div 1&2, Groups A-D; Class II Div 1 & 2，Groups E‑G； ATEX Ex m II T4。

Structure: Poppet valve, valve body material: Acetal for the 27 series and aluminum for the 21 series.

Temperature range: Standard -40 ° F to 140 ° F, 21 series low temperature can reach -4 ° F (-20 ° C).

Voltage: 24 V DC (4.6 W) or 120 V AC (6.8 VA).

Provide 2/2, 3/2, and 4/2 functions, with interfaces ranging from 1/4 "to 2".

The conversion kit can upgrade ordinary valves to explosion-proof on-site.

Air source processing unit (FRL)

ROSS offers a full range of filters, regulators, lubricators, and their combination units, with modular design for easy assembly.

1. Filter

Particle filter: 5, 20, 40 µ m filtration accuracy, polycarbonate or metal cup body, manual or automatic drainage.

Condensed filter: 0.3 µ m or 0.01 µ m, used to remove oil mist and water mist.

Activated carbon adsorption filter: removes oil vapor and hydrocarbons.

Series: Bantam (1/8-1/4 ", flow rate 30 scfm), Miniature (23 scfm), Mid Size (75 scfm), MD3 ™ （92 scfm）、Full‑Size（155 scfm）、MD4 ™ （205 scfm）、High‑Capacity（1000 scfm）。

Optional differential pressure indicator, external automatic drainage, etc.

2. Voltage regulator

Structure: piston type (high flow rate) or diaphragm type (high sensitivity).

Specification: Same series as the filter, with an adjustable outlet pressure range of 0-125 PSI or 0-250 PSI.

Special types: high-precision regulator, remote pilot regulator, high-pressure regulator (400 PSI inlet).

Comes with overflow/non overflow options.

3. Lubricator

Type: Sight Feed or Wick Feed.

Match the flow rate with the corresponding series, equipped with a quick oil filling cup or standard oil filling port.

4. Combination unit

Filtering+pressure regulation: saves space and reduces pressure difference.

Filtering+lubrication: suitable for systems that require lubrication.

Filtering, pressure regulation, and lubrication (FRL): a complete triple component.

Integrated filtration/pressure regulation+lubrication: more compact, such as the MD3/MD4 series.

All FRL units adopt modular clamp connections (MD series), which can be quickly disassembled and assembled, and provide various installation brackets and port blocks.
