Z73H Z73W Knife gate valve

Z73H Z73W Knife gate valve Product introduction

　Z73H Z73W Knife gate valve is suitable for use in more fibrous fluids, eg paper industry and wastewater lines. Knife gate valve is fully sealed with one piece body or elastomer. Z73H Z73W Knife gate valve can also be produced according to its fluid properties. Knife gate valve can be flywheel, gear box, chain wheel, pneumatic actuator and electric actuator. There is rising and non-rising alternatives.

Z73H Z73W Knife gate valve adopts wafer type connection.The wedge type limit stopper can provide sealing the guide nail can provide good guiding function;The anti-adraslve bushings of different materials can be provide according to requirements so as to prolong the service life .Actuators(electric,gear box,pneumatic,hydraulic)can be freely selected.

Z73H Z73W Knife gate valve face-to-face dimensions adopt short series,and light valve is adopted so as to save pipe supporter.During the poening and closing of the Z73H Z73W Knife gate valve,the gate disc can automatically scrape off the adhered stage.Cutoff the medium and residue discharge so that the valve can be operated without blocking.

Z73H Z73W Knife gate valve feature:
• One piece cast body with guides to support gate and seat wedges.
• Provides high flow rates with low pressure drop.
• Various seat and packing materials available.
• Face to face dimension in accordance with CMO standard.
• An arrow is marked on the body indicating the flow direction.

Z73H Z73W Knife gate valve advantage:
- Full open valve provides a very low and smooth transition for flow.
- Flow can be in both direction.
- The valve can be installed in any position. However, it is preferable that the stem is perpendicular to the ground and the flywheel on top.
- Shorter valve length, even at large nominal diameters.
- Economically and conveniently available.
- There are types suitable for high pressures. - Easy to maintain.

Z73H Z73W Knife gate valve application:
This knife gate valve is suitable for liquids that contain a maximum of 5% suspended solids. If it is used for dry solids in gravity feed applications it should be installed with the arrow on the body pointing in the opposite direction to the flow.
Designed for applications such as:
• Paper Industry
• Mining
• Silo emptying
• Chemical plants
• Pumping
• Food Industry
• Sewage treatment
