Category: ODF & SAE CONNECTIONS

Surface treatments applicable: no

Notes:

SAFE: the safety valve can be safely replaced in the system
RELIABLE: simultaneous use of a valve and exclusion of the other
Drop in pressure perfectly compatible with the operation of the safety device during the relieving of both
saturated and overheated steam.
FULL SEALING CAPACITY No leaks thanks to double sealing O-ring on body’s junction

Description

The changeover series 42000 is used as service device to mount 2 safety valves with a single operation, on the system so as to speed up maintenance and replacement of the valve when one of the two is used.

Main features

SAFE: the safety valve can be safely replaced in the system
RELIABLE: simultaneous use of a valve and exclusion of the other
Drop in pressure perfectly compatible with the operation of the safety device during the relieving of both saturated and overheated steam.
No leaks thanks to double sealing O-ring on body’s junction: FULL SEALING CAPACITY

Applications

The changeover of the 42000 series are used as service taps for a pair of safety valves and allow you to keep one valve connected to the system by isolating the other. In this way, the user can perform maintenance on the isolated valve for periodic verification or replacement, keeping at least one valve always operational for the safety of the system.

Components

The main components of the changeover valves in the 42000 series are:

Body made of hot-forged brass to EN12165-CW617N
AISI 303 stainless steel control lever
Sealing gaskets made of HNBR and Neoprene
Cap protecting the AVP steel lever, with galvanized protective coating, complete with sealing gasket
Austenitic stainless steel for the screws securing the two parts of the body of the faucet
Threaded revolving ports for connecting the safety valves to the AVP steel spare changeover faucet, with galvanized protective coating
