I TYPE SINGLE SEAT VALVE


IMPLEMENTATION
I-SSV is a single seal valve offering a wide range of implementation areas as a dual or triple way stop valve or three or five way flow diversion valve, with a flexible design that operates with air.

OPERATION PRINCIPLE
The valve is controlled remotely with pressurized air. Few number of simple moving parts in its content make it a reliable and long-lasting valve.

STANDARD DESIGN
I-SSV consists of an actuator, gaskets, cover and valve bodies. All components are combined with clamp rings and a shaft terminal fitting.  The valve is only partially combined when shipping to simplify its installation.  The valve is welded as a standard.

ACTUATOR FUNCTION
(NC) opened by pulling up the piston as a standard, optionally normally open (NO) and Air/Air (A/A), dimensions 25-101,6 mm
/ DN25-100. Actuator for the intermediary position of valve cover as an option, dimensions 25-101,6 mm / DN25-100.

Note:
I-SSV valve is designed, tested and approved according to EHEDG standard.
