The over/under pressure VSP 273 Safety Valve has been engineered in order to protect silos and hoppers against occasional over - and under - pressures which can be generated by :
Pneumatic filling
Blockage of the vacuum cleaning filter
Fermentations
Variations in temperature
Condensation
The VSP 273 has been designed to only work on roof.

The Valve is designed for precise control in pneumatic control circuits. It can be used as a relay valve to sequence specific signal operations or as a relief valve to limit pressure in a pneumatic system.
Fixed or adjustable pressure settings are available; the pressure range is 0-20 PSI. To adjust the valve, turn the adjusting screw clockwise to reach zero adjustment. Then turn the adjusting screw counterclockwise to the desired relieving or sequencing pressure. The valve can be supplied with an allen-wrench adjustment or a knob. The valve has straight ports for 1/16” I.D. flexible tubing, barbs for 1/16” or 1/8” tubing are also available.

Tech-Taylor Valve
The Tech-Taylor Valve is a dual or triplex free ball check valve used to isolate pumps mounted in parallel.
Features
-Self operating - no actuator required
-Fully rubber lined slurry valve
-Minimal pressure drop

The closing system consists of a self-cleaning ball which is lifted by the fluid and guided to a lateral housing, completely out of the way. This system ensures an unrestricted flow, even for liquids carrying waste materials, without risk of a blockage. This all-purpose range is also suitable for use with aggressive liquids and in industrial processes.

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”.
