Descrizione del prodotto<\/h2>\n

A valvola a sfera pneumatica<\/strong> in 316 stainless steel: a one-piece valve body with a rack-and-pinion air actuator bolted straight onto it.<\/p>\n

There is no bracket and no coupling.<\/strong> The ISO 5211 mounting pad is part of the valve body itself \u2014 cast as one piece with it, not bolted on afterwards. That single fact is why this valve outlasts most small automated ball valves, and it is worth two minutes of your time to understand why.<\/p>\n

Why No Bracket Matters<\/h2>\n

Most small pneumatic ball valves on the market are four separate parts stacked on top of each other: the valve, a steel bracket, a coupling, and the actuator. Every one of those joints is a place where things go wrong.<\/p>\n

Valve + bracket + coupling + actuator<\/th>\nQuesta valvola<\/th>\n<\/tr>\n<\/thead>\n
The bracket bolts work loose.<\/strong> Every cycle puts torque through them. Nobody checks them until the valve stops turning.<\/td>\nNo bracket to loosen.<\/strong> The pad is part of the body.<\/td>\n<\/tr>\n
The coupling can sit off-centre.<\/strong> A misaligned coupling wears the stem and the actuator shaft on every stroke.<\/td>\nNothing to misalign.<\/strong> The actuator seats directly on the integral pad, concentric with the stem.<\/td>\n<\/tr>\n
Four parts to source, four to stock, four to blame when it fails<\/td>\nValve and actuator, assembled and tested by us before it ships<\/td>\n<\/tr>\n
Taller assembly \u2014 harder to fit in a machine frame<\/td>\nShorter. The actuator sits down on the body.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

The pad is ISO 5211 standard<\/strong>, so it is not a proprietary fitting \u2014 you are not locked into us for the actuator.<\/p>\n

On\/Off Only \u2014 Do Not Buy It to Throttle<\/h2>\n

This valve opens and it closes. It is not a control valve.<\/strong> We do not offer a positioner for it, and we will not sell you one that is half-open all day.<\/p>\n

A ball valve held part-way open puts the full flow across one edge of the ball and one edge of the seat. The PTFE cuts, the seat leaks, and you are back to us in a year. If you need to modulate flow rather than shut it, tell us what you are trying to do and we will say honestly whether we have the right valve for it.<\/p>\n
