CHECK VALVES

ART. 001
The check valve has been one of the strong points of Ratti’s production. In fact, article 001 was the first product developed back in 1974.
This valve is filed from a full sturdy 316L bar of European certified make.
The valves have cylindrical gas female die connections, and the diameters available are as follows:1/4”, 3/8”,1/2”,3/4”, 1”, 1.1/4”, 1.1/2” and 2”.
Inside the valve his piston is supported on two points, in order to keep excellent alignment during any assembling position; these two supports are furnished with special millings to allow the passage of fluid with as least loading losses as possible, in comparison to the classic “drilled disc”.
The standard capacity of the valve is made in certified PTFE but it is also available in silicone, glass, copper or stainless steel upon request.

ART. 048
This valve was projected by Ratti to facilitate the dismantlement and cleaning process, in observation of pharmaceutical and bio-technologic plant regulations.
Innovation is the result of the use of an auto-aligning PTFE piston, and the conic support spring.
They are the only components present inside the valve.
The internal finishing is strictly lower than 0,4 Ra, the external part of the valve is polished and laser-marked indicating the direction of the assemblage, the dimension of the valve, the type of steel used, and the number of the tapping from the steelworks.
The semi-bodies are joined through a Tri-Clamp connection and they are filed from a sturdy 316L stainless steel full bar of European certified make.
The dimensions available are as follows: 1/2, 3/4”, 1”, 1.1/2”, 2” and 2.1/2”.
