Benefits:

ARES

Ares-Atena pneumatic valve - benefits - ARES

1. Seal placed in the cylinder rather than on the piston.
Longer stroke of the actuator and shutter will be achieved, granting higher flow rate (less flow loss).
Less wear of the seal.

2. Piloting head inserts in 303 S.S.
Increases considerably the corrosion resistance caused by external agents.

3. Starting from DN63 metal piston with CHEMICAL NICKEL coating (10-15 micron).
Reduces the wear of the piston due to the achievement of a greater surface hardness (700-750 HV).

4. Seals pre-loaded by spring.

Guarantee of the recovery of the gap due to the wear caused by the sliding of the shaft avoiding leakage towards the outside part.
Allow to maintain energized the “chevron” seals (V) compensating the dimensional changes even in case of huge temperature excursions.

5. CHEVRON seals (V shape) with 5 seals in the lower part of the spring and 3 seals in the upper part. 

It ensures a perfect tightness even after a high number of cycles

6. Rolled shaft.
Less wear of the seals due to the low roughness (0,1 micron Ra) which facilitate the sliding of the shaft.

7. Longer face to face.

Better fluidodynamic with reduction of the turbulences.

8. Oscillating / self-aligning shutter.

It fits perfectly to the valve body ensuring the maximum tightness.

ATEX Certificate.
Installation is allowed in a potential explosive environment.

PED Certificate.
Full compliance with European Safety Standards for Pressure Equipment.

GENERAL FEATURES:
Threaded valve ends, as per EN 10226-1 Rp (ex ISO 7/1) for Ares valves; ISO 228/1 for Zeus valves. Other types available on request.
Assembling is possible in all positions: upright, flat or angled.
Range available from 3/8” to 2” in the Double Acting versions, Spring Return N.C. from above and below the plug, Spring Return N.O. from below the plug.
According to 2014/68/EU “PED”.
2014/34/EU ATEX configuration to request at time of order.
The variations in the actioning of the valve, the several combinations and the possibility to intercept the fluid from above or below the plug, originate multiple versions of the automatic valve.
In the table below are indicated the standard versions with the main parameters.
On the basis of the kind of valve and the variations of pressure ΔP that must be intercepted, the necessary control pressure can be individuated, and consequently, the code for the corresponding valve.
On request: versions for vacuum and oxygen service.

CONTROL MEDIA:
Driving media: compressed air, lubricated or dry, gas or neutral media.
Ambient temperature: -10°C to +60°C

OPERATING MEDIA:
Air,water, alcohol, oil, petroleum products, saline solutions, steam, etc. (as long as compatible with A 351 CF8M O CuSn5Zn5Pb5-B).
Pressure from 0 to 16 / 25 bar (steam from 180°C, from 0 to 10 bar) depending on the size and model chosen (see following pages).
Temperature from –10°C to 180°C.
Max. viscosity 600 cst (mm2/s).
