Starting from the title you can easily assume that OMAL Automation has something to do with pressure and the managing of the media transportation. But mentioned in this way it is limiting: the product range in fact includes scotch yoke pneumatic actuators – the core product at the beginning of company activity in 1981 – pneumatic valves (angle-seat and coaxial), butterfly and ball valves, both floating and trunnion mounted till 24”. In a few words, OMAL can offer the “complete package” for the process automation anywhere and anyhow a media is involved, both in industrial and OIL&GAS applications.
One main concept is common in each product: it has been produced following company pay-off “Empowered Performance”. It means to offer reliable products that are really high-quality, containing tangible and evincible advantages.
HERCULES high pressure valve
Also for HERCULES series project the aim was to have an empowered product that was absolutely suitable for high ciclicity purposes. That’s why OMAL engineers started a study about new materials and system that could have allowed an added value in term of reliability and durability. The results of this 1 year-research is shown on HERCULES: a rolled stem with two bushing-guides (in “Powerammide” compound), a harder O-Ring properly developed for gas high-pressure and a special material (“Extreme”) sealing seat for the ball, just to give you some examples.
It is important to underline that the receipts of Powerammide (that is a special blend of polymers and aramid filler) and Extreme (Aromatic polyamide long chemical structure) have been developed in OMAL and they have been chosen after long test-sessions and comparisons with other materials. The name of these two materials are commercial name created at OMAL as a further signal of exclusivity for their availability. Furthermore, the two bushes in Powerammide, that are moulded internally in OMAL, have the proper composition and hardness that avoid the bending of the stem while working under high loads, allowing a self-centring of the stem in a perfect axial way.
All these features allow a low-friction among the components, less torque in the system and as consequence high ciclicity and durability.
The “automated” version of HERCULES has antistatic-device, fire-safe design and, upon request, ATEX certificate. This ball valve is appropriate to a lot of high-pressure media application, like wash-water systems or hydraulics oils, but it is the PERFECT solution for CNG: compressors, skids, distribution lines, dispensers for vehicle refuelling. HERCULES Series is available both in carbon and stainless steel, from 1/8” to 2” for pressure till 500 bar.
The construction of the valve could seem simple at first glance from the outside. But, in addition to the features we have described, you have to know that this kind of “little” product must bear on certain surfaces a force-level similar to the load of a big SUV while handling the fluid. So, a careful project – with attention to details and materials – and a controlled production process are needed for an optimal result: this is the OMAL way of working.
