KNIFE GATE VALVES

 

Bulk Technik can offer two types of knife gate valves: Flow Control (FC) or Flow Seal (FS).

 

The Flow Control range of knife gate valves is suitable as a discharge valve of a silo or hopper when used with gravity feeding dry granular products. These valves can be used to reduce the product flow out of a silo or to stop the flow completely. The FC series of knife gate valves are supplied with either a hand wheel or a pneumatic or hydraulic cylinder. They have a square, mild steel frame with a 3Cr12 blade, a stuffing box type seal and replaceable material deflector inserts that protect the valve sealing strips. In addition to the standard range, custom designed knife gate valves are supplied on request as well as those manufactured from stainless steel.

 

The Flow Seal series of knife gate valves are fully imported from AKO in Germany. These knife gate valves are suitable for use with liquids and non-abrasive powders up to a pressure of 10 bar (higher pressures on request). They are supplied with standard SABS 1123 or ANSI flanges with sizes ranging from 50 NB to 1200 NB. The blade of the knife gate valve is operated with either a handwheel, pneumatic actuator (single acting or double acting) or an electric bevel gear. The blade is manufactured from stainless steel, the valve body is supplied in either cast steel or stainless steel and both soft and metal seals are available.
