Function, section
Valves of type Z1S are direct operated check valves of sand-
wich plate design.
They are used to check a flow leak-free in one direction and al-
low free flow in the opposite direction.
The stroke of poppet (3) is limited by spring plate (4). An in-
tegrated spring (5) supports the closing movement. When no
fluid flows through the valve, spring (5) holds poppet (3) in the
closed position.
Type Z1S 10 ..-3X/V (with metal seal)
This valve version is provided with a metal seal between pop-
pet (3) and housing (1). Valves of this version are particularly
suitable for applications that involve operating pressures higher
than 100 bar and flow velocities of more than 4 m/s.
Type Z1S 10 ..1-3X/VW4 (with soft seal)
This valve version is fitted with a soft seal between poppet (3)
and housing (1) and provides hermetic sealing. Valves of this
version are particularly suitable for applications with flow veloc-
ities of up to 4 m/s and low operating pressures.
