Product Introduction
High flow due to angle seat design
Anti-waterhammer design (fluid entry under the disc)
Standard gland packing suitable for Vacuum up to 10
Wide range of piston-type operators (40 - 50- 63 - 90 - 110 -125 -150 - 160mm dia.) rotatable through 360°, for maximum performance at different minimum pilot pressures
High performance, maintenance-free stuffing box
Valve body material: AISI 304,AISI 316, AISI316L and Gunmetal
Valve ends: Female thread, Male thread,Butt welds, Socket welds, Flange ends, and Tri-clamp ends.
Range available from 3/8”to 4” in the double acting versions, spring return N.C.from above and below the seat, spring return N.O. from below the seat.
The variations in the actioning of the valve, the several combinations and the possibility to intercept the fluid from above or below the seat, originate multiple versions of the automatic valve.
On the basis of the kind of valve and the variations of pressure that must be intercepted, the necessary control pressure can be individuated, and consequently, the code for the corresponding valve.
