It is the actuated version of our manual extended butt weld valve. Everything about the body is the same; the difference is the actuator on top instead of a lever.<\/p>\n

Read the two sections below before you order.<\/strong> One tells you why the ends are long. The other tells you what pipe this valve fits, and what pipe it does not.<\/p>\n

Why the Weld Ends Are Long<\/h2>\n

A ball valve seals on PTFE. PTFE begins to degrade well below the temperature of a weld pool.<\/p>\n

On a standard butt weld valve, the weld sits close to the body \u2014 and the heat travels down the metal into the seats. That is why people weld a valve in, pressure-test the line, and find the valve leaking. The seals were cooked during installation, before the valve ever saw a drop of product.<\/p>\n

The extended ends move the weld away from the seats.<\/strong> The extra length is the heat sink. You weld the valve in fully assembled \u2014 no dismantling, no removing the ball and seats.<\/p>\n

And because the body is three-piece, you can still take it apart afterwards for servicing: undo the body bolts, lift the centre section out, replace the seats, put it back. The ends stay welded in the line.<\/strong> Nothing gets cut out.<\/p>\n

The Air Actuator<\/h2>\n

The valve is turned by a rack-and-pinion pneumatic actuator in aluminium alloy, mounted directly on the valve\u2019s \u0627\u0644\u0645\u0639\u064a\u0627\u0631 \u0627\u0644\u062f\u0648\u0644\u064a ISO 5211<\/strong> pad \u2014 no adapter kit, no field re-piping.<\/p>\n
