BI-DIRECTIONAL KNIFE GATE VALVE

The HB model knife gate is a bi-directional valve designed for general industrial service applications. The design of the body and seat assures non-clogging shut off on suspended solids in industries such as: Wastewater treatment plants Chemical plants Food and Beverage etc. Sizes: DN 50 to DN 300 (larger diameters on request) Working pressure: DN50 to DN 300:16 kg/cm2 Standard flange connection: DIN PN 16 Other flange connections: on request Directives: DIR 98/37/CE (MACHINES) DIR 97/23/CE (PED) DIR 94/9/CE (ATEX)

Face to face dimensions acc. to EN558-1 serie 20 (replaces K1 DIN3202) up to DN500.
All valves are tested prior to shipping in accordance with the standard developed by the Quality Control Department at ORBINOX.

DESIGN FEATURES

BODY: Wafer stylecast monoblock design internally machined up to DN 500 with reinforced ribs in larger diameters for extra body strength. It allows its installation as end of line from DN50 to DN300. The design has been developed by a new manufacturing process that machines the inside part of the body, allowing more control in the different dimension tolerances. This allows a perfect adjustment of thebody-gate-seal, reducing the torque that keeps the tightness and avoiding any build up of solids that would prevent valve from closing. The design changes to two part bolted body internally machined from DN 600. Full port design for greater flow capacity and minimal pressure drop. The gate guides on full stroke ensure bi-directional shutoff. Standard EPDM o-ring on flange connection of the valve forsealing. GATE: Stainless steel gate, as standard. Gate is polished on both sides for a greater seal between the gate with both packing and seat. Gate is fully guided in the body allowing for bi-directional service. PACKING: Standard PTFE impregn.synth fibre (ST) with EPDM o-ring for better shut-off. Long-life braided packing is available in a wide range of materials. NON RISING STEM: The standardstainless steel stem offers a high and long corrosion resistant life. ACTUATORS: All actuators supplied by ORBINOX are interchangeable, and supplied with an standard mounting kit for easy installation on site. YOKE or ACTUATOR SUPPORT: Made of EPOXY coated steel (stainless steel available on request). Compact design makes it extremely robust even under the most severe conditions. EPOXY COATING: Theepoxy coating on all ORBINOX cast iron and carbon steel valve bodies and components is electrostatically applied making the valves to be corrosion resistant with a high quality finished product. The ORBINOX standard colour is RAL-5015 blue. GATE SAFETY PROTECTION: ORBINOX automated valves are provided with gate guards in accordance with EU Safety Standards. The design feature prevents any objectsfrom being caught accidentally while the gate is moving. OTHER MATERIALS On request, following materials can be also supplied: Body: - CF8M Gate: - AISI 316 or 316Ti - 2205 Stem: - AISI 316 or 316 Ti
