Description
Introduction
The Zasflo Uni-Directional Wafer Knife Gate Valve is a highly durable, manual wheel-operated flow control solution engineered for demanding general industrial service applications. Designed with an optimized body and seat structure, this valve provides a reliable, non-clogging shut-off mechanism specifically tailored for media containing suspended solids.
Key Features
– Broad Size Range: Available in manual wheel-operated sizes from DN50 up to DN1000.
– Robust Manual Drive: Features an epoxy-coated cast iron handwheel, complete with a stem, stem nut, and stem protector for reliable operation.
– Versatile Sealing Options: Compatible with multiple resilient seals including EPDM, NITRILE, FKM, and SILICONE, with custom materials like hypalon or natural rubber available for specialized requirements.
– Standardized Compliance: Face-to-face distance aligns with the MSS-SP-01 standard, and flange drilling complies with EN 1092 PN10 and ASME B16.5 (class 150).
Benefits
Zero Clogging Design: The internal body design actively prevents any build-up of solids in the seat area, ensuring uninterrupted operation.
Optimized Flow Dynamics: Delivers consistently high flow rates while maintaining exceptionally low pressure drops across the system.
Reverse Pressure Resilience: Designed with gate support guides that allow the valve to withstand up to 30% of its rated working pressure from the opposite direction without sustaining any damage.
How to Use & Applications
General Use: Suitable for liquids containing a maximum of 5% suspended solids. The valve body features a clearly marked arrow indicating the standard flow direction for correct installation.
Dry Solids Installation: When utilizing this valve for dry solids in gravity feed applications, it must be installed with the directional arrow on the body pointing in the opposite direction to the actual flow.
Core Industries: Ideal for deployment in the Paper Industry, Mining, Silo Emptying, Chemical Plants, Pumping Stations, the Food Industry, and Sewage Treatment facilities.
Why Choose This Product
Manufactured under strict ISO 9001:2015 quality standards, every Zasflo Knife Gate Valve undergoes rigorous hydrostatic testing before dispatch. The body is tested at 1.5 times the working pressure, and the seals are tested at 1.1 times the working pressure, ensuring peak watertight integrity and long-term industrial reliability.
