Overview
Multiway cock PN 100 (7MF9004-1P.) for differential pressure transmitters
The multiway cock PN 100 can be flanged to pressure transmit-
ters for differential pressure.
■
Benefits
• Version available for aggressive liquids, gases and vapors
• Robust design
• Oil-free and grease-free version possible
• One-hand operation
■
Application
The PN 100 multiway cock is available in versions for aggressive
and non-aggressive liquids, gases and vapors.
■
Design
The multiway cock can be flanged with four screws to pressure
transmitters for differential pressure.
The PN 100 has 2 process connections and one blow-out con-
nection. A steel version of the multiway cock is available for non-
aggressive media, and a stainless steel version for aggressive
media. The housing is forged in one piece. The switching lever
is removable.
Sealing can be improved during operation.
Note: An accessory set is always required for flanging of the
multiway cock to a differential pressure transmitter.
