Mecesa AM needle valve with locking system
Needle valve with handwheel, locking system and back seat for isolating and regulating instrument lines.
The AM is Mecesa’s standard needle valve. A locking system prevents unintended operation and the back seat seals the stem when the valve is fully open, so the packing can be serviced under pressure. It is available with threaded ends or with Megalok double-ferrule tube connections.
