Parts matter, whatever your service environment. Our standard 316SS stainless steel internals offers superior corrosion protection and resistance to sulfide or hydrogen-induced cracking, providing reliability and performance over a long service life. These parts conform to NACE MR0175 / ISO 15156:2015 specifications. For highly corrosive applications, such as wet H2S service, Duplex or Super Duplex steel internals are available to protect against general and localized corrosion.

Canalta has endeavored to ensure that our parts and accessories offerings are interchangeable with the current industry standard orifice fitting brand, making Canalta Orifice Fitting internals suitable for re-builds and re-works of our competitors’ product lines.

HNBR O-ring Seals on both the body and seal bar come standard with all Canalta Dual Chamber Orifice Fittings. This feature eliminates nuisance gasket maintenance and clamping bar screw breakage, while providing superior sealing capability. The O-rings incorporated are standard shelf sizes and can be supplied in a wide variety of compositions. Gaskets are also available and can be used when preferred or required.

The Soft Seat Valve Seal is available for all dual chamber models. Particularly suited to low pressure applications, this unique design enables a bubble-tight seal between the upper and lower chambers without the need for frequent lubrication. The specially machined seal channel helps prevent O-ring dislocation, and the O-ring seals incorporated are available in a wide variety of compositions.
