DN: 50 - 1200
PN: 10 (PN 16 upon request)
Exterior design: knife goes through the seal area
Main characteristics: monobloc body, circular, total passage: enables a high flow capacity with low load loss, gate with rounded edges: prolongs the working life of the rings and packing, interchangeable drives (hand wheel, electric actuator, pneumatic actuator)
Seat: NBR; EPDM, metal-metal Applications: ideal for installations handling liquids containing suspended solids and wastewater (mining, chemical treatment, water treatment, etc.)
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.
