APPLICATION

General use : Pulp production, water, water treatment, waste water, chemical industry

( powdery or crystallizing products), wine-producing, pulverized products

(cement work, pneumatic transport, stocking).

GENERAL CHARACTERISTICS


- Function ON/OFF or regulation.
- Wafer threaded mounting.
- Unidirectional tightness, direction indication thanks to the arrow on the body.
- Small retention zone: the gate is guided in the body and has little clearance.
- Gland assembly: packing and O-ring (same materials as seat joint) to assure

the elasticity and decrease the operating torque.
- Small head loss.
- Possibility to regulate thick fluids with the adaptation of a diaphragm ring.

WORKING CONDITIONS

Maximum working pressure :

DN 50-250 : 10 bar.

DN 300-450 : 7 bar.

DN 500-600 : 4 bar.
