Angle-Seat Valve
Carefully read the installation and operating
instructions. Attention must be paid to the
application conditions and the technical data as
specified in the data sheet. Complying with
these instructions will ensure perfect operation
and a long service life.
Application and operation of the device must
ensue according to the general terms of
technology. Appropriate measures must be
taken to avoid unintended operation or
unapproved impairment.

Installation
The applicable safety regulations must be
observed.
! Pipelines must be contamination-free.
• Installation as required, but preferably with
actuator upright. Observe flow direction.
• Connect valve. Observe aligned pipes.

• Unscrew actuator on nipple from valve body.
• Only by Stainless steel body: Grease over
nipple thread with „GLEITMO 810".
• Screw nipple and actuator into valve body.
• Connecting the control fluid for
control function:
– A, to the lower
– B, to the upper
actuator port with G 1/4" thread.
(Connection can be rotated by 360º).
The Pilot valve must be connected to the
actuator with a hollow screw (Types 6012 P,
6014 P) and the control fluid must be connected
to port P of the pilot valve.
