| Installation | Installation may be performed as required; however, it is recommended that the actuator be positioned facing upwards. The valve may be installed in any orientation, provided that valve operation remains unimpeded. For internally threaded models (C*), installation should be performed in accordance with standards ISO 228/1 and ISO 7/1. Installation and maintenance instructions for the valve are included within the product packaging for each unit. | |

High flow due to angle seat design;
Anti-waterhammer design (fluid entry under the disc);
Standard gland packing suitable for Vacuum up to 10⁻² mbar
Wide range of piston-type operators ( 40 - 50- 63 - 90 - 110 mm dia.) rotatablethrough 360°, for maximum performance at different minimum pilot pressures;
High performance, maintenance-free stuffing box;
Valve body material: Gunmetal;
Valve ends: Female thread, Male thread,Butt welds, Socket welds, Flange ends, and Tri-clamp ends.
Range available from 1/2”to 2-1/2” 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.
