EMERSON. CLARKSON ZERO POCKET KNIFE GATE VALVES MODEL ZP300Designed for the extremes of oil sands applications, the zero pocket provides an uninterrupted flow across the valve, increasing service life and minimizing wear on downstream components Size range: Temperature rating: Pressure rating: Compliance to: Face to face: GENERAL APPLICATIONS The Zero Pocket (ZP300) has been specifically designed to meet the high pressure and highly abrasive applications such as oil sands processing and tailings. Designed to the requirements of MSS-SP135 in Class 300, the ZP300 has many features proven to provide longer service life, lower maintenance and lower cost of ownership compared to other styles of knife gate valves.

CLARKSON ZERO POCKET KNIFE GATE VALVES MODEL ZP300 TWO STYLES OF INTEGRAL FLOW RINGS EXTERNAL RING • 17-4 ph S/S • Replaceable and rotatable. • Not for dead-end service. INTERNAL RINGS • 17-4 ph S/S or white iron per ATSM A532 • Replaceable and rotatable. • Suitable for dead-end service (with 17-4 ph ring only). Why “Zero Pocket”? The ZP300 valve with its Zero Pocket port design generates less disruption to pipeline flow than valves with obstructions in the flow path, offering superior life for the valve with a lower cost-ofownership. Additionally, the smooth flow minimizes wear on the downstream...

SSEC: SYNERGISTIC SURFACE ENHANCEMENT COATING Well suited for use in applications where corrosive media or abrasion is a problem, SSEC is ideal for applications with sticky, viscous media, scaling/plating or where galling is a problem. The low coefficient of friction eliminates "stick-slip" problems, reduces drag and increases sleeve life. Often improves micro finish of a gate or body. SSEC is a synergistic coating that combines the advantages of anodizing, plating or thermal spraying with the controlled infusion of polymers, dry lubricants and other materials to provide an entirely new composite...
