Valves with steel manifolds :
Manifolds are manufactered from high quality steel and are externally coated by zinc plating strengthened with yellow passivation. They are reccomended for heavy duty applications where the maximum rated pressure is frequently achieved.

Valves with aluminium manifolds :
Manifolds are manufactured from high strength wrought aluminium, and can be black anodized upon request. They can be employed where the maximum
rated pressure (which is indicated for each valve type) is not frequently reached, or for regular operation at lower pressure.

Cartridges and other internal or external parts:
They are manufactured with top quality steel processed with the most advanced machinery, which combines high production capacity with full and precise control of dimensions. Heat treatments of steel components, with particular care for poppets and seats, are performed by automatic and highly computerized equipment specifically developed for these production cycles. All external steel parts are protected by zinc plating strengthened by yellow passivation.

Ports:
G sizes (BSPP) from G 1/4 to G 1 1/4 are standard; SAE sizes (straight thread, with O-Ring), JIS or metric ports can be manufactured upon request.

Seals:
O-Rings: are made with acrylonitrile/butadiene, commonly called BUNA-N (or NBR, according to ASTM), standard for temperatures between -30°C and +100°C (-22°F and +212°F). Viton seals are recommended for higher temperatures. Back-Up Rings and Slide Rings: reinforced poly-tetrafluoroethylene (PTFE), or BUNA-N (NBR) as well.
