Diaphragm valve T7, solvent sockets, EPDM diaphragm
- Greater safety
due to higher PN
- Position indicator
shows valve opening status
- Complete drainage
due to special body geometry
- Locking handwheel
protects against misuse
Description
The Praher Plastics diaphragm valve T7 is characterised by its remarkable service life and outstanding ease of servicing.
The new housing shape allows liquids to drain away completely. The handwheel is ergonomically shaped, non-slip and equipped with a lockable catch. An end stop prevents the valve from sticking if it is open for a longer period. The T7 has a torque limiter to prevent the valve from being overtightened.
