Frequently Asked Questions

What is a knife gate valve?

A knife gate valve is a linear motion valve with a sharp-edged blade (knife) that cuts through media to achieve shut-off. It is designed for thick, viscous, and abrasive media like slurry, pulp, wastewater, and mining tailings. The knife edge can cut through solids that would jam conventional gate valves. Knife gate valves are available in wafer and lug body styles.

What is the value of knife gate valve PN10?

Supreme Valves knife gate valve PN10 wafer type prices (from factory India): DN100 (4 inch) manual hand wheel = ₹9,737 per unit, DN150 (6 inch) manual = ₹12,194 per unit, DN200 (8 inch) manual = ₹19,838 per unit. DN100 with electric actuators electric actuator (24V DC) = ₹34,737 per unit (valve ₹9,737 + actuator ₹25,000). GGG40 body, SS304 knife, EPDM seat. Delivery 2-3 weeks.

What is GGG40 material in knife gate valves?

GGG40 is a ductile iron (also called nodular cast iron or spheroidal graphite iron) grade per DIN EN 1563. It has minimum tensile strength of 400 MPa and elongation of 15%. GGG40 is equivalent to ASTM A536 60-40-18. It offers good strength, ductility, and corrosion resistance at lower cost than steel. Widely used for valve bodies, pump casings, and pipe fittings.

What is wafer type knife gate valve?

A wafer type knife gate valve is designed to be sandwiched between two pipe flanges using through-bolts. It has no flanges of its own, making it lighter, more compact, and more economical than flanged or lug type valves. Wafer knife gate valves are suitable for PN10 and PN16 flange ratings. They are the most common configuration for knife gate valves in wastewater and slurry applications.

What is electric actuators actuator for knife gate valve?

electric actuators is a leading German manufacturer of electric actuators for industrial valves. The electric actuators actuator offered with this knife gate valve operates on 24V DC power supply with ON-OFF control and proximity sensors for position feedback. It provides automated open/close operation, remote control capability, and position indication. electric actuators actuators are known for reliability, IP67/IP68 protection, and long service life.
