Needle valve Ratti G e C snc

Pin valves

This pin valve is the evolution of article 009, one of the first articles projected and constructed by Ratti.

It immediately differentiates from other valves on the market due to the fact that there is no packing between the body, the valve and the support of the stem.
This solution, introduced over 30 years ago, has allowed us to guarantee a longer life of the valve, in fact the lack of an elastometer in such a critical position, and the realization of a metallic support, provides the valve with greater reliability in terms of tightness.

The only packing present in these valves is the PTFE compass, positioned on the top to support the stem.

The external part of the valve body has been completely re-designed from a "square" shape to a more "round" shape, in order to eliminate the external edges, thus reaching a better shape and making the constructive process more efficient, reliable and economical.

The valve is filed from a full sturdy 316L full bar of European certified make.

In the "053" version the connections are gas cylinder female die screw-cut and the diameters available are as follows: 1/4", 3/8",1/2",3/4", and 1".

In the "049" version the connections are of 3/4", 1", 1.1/2" and 2" "Tri-Clamp" type and the gauges are the same of the diaphragm valve (Art. 061) to favour interchangeability without modifying the plant.

Upon request, Articles 053 and 049 may be furnished with fastenings to be welded.
