The mechanical pneumatic valves can be operated either by a mechanism or by an operator and are assisted by a series of complementary valves that perform very important functions in pneumatic circuits. They are therefore fundamental components for the correct operation of any pneumatic system.
Mechanical and manual pneumatic valves for pneumatic circuits
Mechanical valves: supplied by Waircom
As well as having various manufacturing technologies available and the most up to date machinery, Waircom has a precise production organization structure that allows it to manufacture both mechanical spool valves and poppet valves. We also produce mechanically or manually actuated mini valves with pneumatic functions, mini ball valves and pedal actuated valves.
In addition to these, there are the complementary valves, which are indispensable components if a pneumatic circuit is to operate correctly. We make selector valves, quick exhaust valves, check valves, block valves and amplifier valves.
Lastly, our catalogue also includes pneumatic logic elements and flow regulators
Waircom: certified quality
All the series of mechanical valves, mini valves and complementary valves produced by Waircom comply with European and international regulations, including the European Union ATEX directive regarding the resistance and safety of equipment intended for use in manufacturing and carrying out work in potentially explosive environments.

Waircom places its expertise at your disposal.
◘ SERIES M
| Minivalves series "M" are produced in the 2/2 and 3/2 pneumatic functions in both side and bottom ported versions, with push-in fittings on body valve for pipe Ø 4 mm or M5 threaded connections; the version G 1/8 bottom ported is also available. Thanks to the suitable adapter types MCS-SA and MCS-SAD these minivalves support the "BRETER" Ø 22 mm actuators for panel mounting. The same actuators can control 1 or 2 minivalves, thus it's possible to obtain the 3/2, 5/2, 5/3 open centre and the 5/3 pressure centre pneumatic functions.
◘ SERIES EK
|Valves series "EK" are produced in the 3/2, 5/2 and 5/3 pneumatic functions; the kind of construction is based on a balanced spool. In the mechanically actuated version these valves are available only for the size G 1/8 and G 1/4, while the manually actuated versions are available in the different sizes and they are suitable for panel mounting (except for size G 1/2).
◘ SERIES CA
|Valves series "CA" are produced in the 2/2, 3/2, 3/3, 5/2 and 5/3 pneumatic functions. The poppet kind of construction and the very rugged control allow the valve to stand high stress. The push-button and mushroom controls are available only in the 3/2 monostable pneumatic functions for the size G 1/8.
◘ SERIES PC
|Pedal actuated valves series "PC" are produced in the 3/2 and 5/2 pneumatic functions, with or without protection, and they are based on direct acting poppet valves and direct acting or pilot assisted spool valves in the sizes G 1/8 and G 1/4.The catch on the pedal allows obtaining the bistable pneumatic functions, while the safety device avoids the accidental actuation of the same pedal.
◘ COMPLEMENTARY VALVES
|Complementary valves are very important components of the pneumatic circuits. This group includes the:
- SHUTTLE VALVES: these valves are used when there is the necessity to convey, in one pipeline, two pneumatic flows coming from two different pipelines without any interference; in fact the compressed air flows from one of the two inlet ports to the working port while the second inlet port is excluded.
◘ SERIES EL
|Pneumatic logic elements series "EL" are produced in the following No.5 basic functions: OR, AND, YES, NOT and MEMORY, with push-in fittings for pipe Ø 4 mm, and the pressure indicator is on body valve as standard. These elements can be mounted both separately (line mounted thanks to the No.2 holes on body valve) than on manifold bracket. The pneumatic logic element NOT is a threshold component and the pressure triggering value is 0,6 bar (at 6 bar).
◘ SERIES UR
|Flow regulators series "UR" are produced in three different versions, unidirectional (type "URG") - bi-directional (type "URF"), to have a precision in-line regulation; unidirectional (type ŸUREŒ), when it’s necessary a standard in-line regulation with reduced dimensions, and in the silenced exhaust version (type ŸURSŒ). In-line precision flow regulators type ŸURGŒ-ŒURFŒ are available in different adjustment scale in the size G 1/8 (see the flow charts).
◘ SERIES WB
|Block valves series "WB" are produced in the 2/2 - G 1/8, G 1/4 and G 1/2 monostable pneumatic functions in both the uni- and bi-directional versions. The working of the block valve consists in avoiding unexpected depressurisation of the cylinder’s chamber due to lack of compressed air at the piloting port. For a correct functioning of the block valves we suggest to mount them directly on the cylinder.
◘ SERIES XVF
|The type "XVF4" identifies a 3/2 N.C. amplifier valve that changes low pressure signals into pneumatic signals (1 ÷ 8 bar).Valve type "XVF5" is instead a 3/2 N.O. amplifier valve that changes negative pneumatic signals into pneumatic signals (1 ÷ 7 bar).Both of them are suitable to pilot directly the valves series "UDS" and "UK" with the same mounting than solenoid valves series "UL". For single mounting there is the sub-base type "XVB" (see on page 2.8) while for manifold mounting there are the bases type "ULP" (see on page 2.7).
