SINCE 2009,HNA has been an integrated engineering & manufacturing specialist recognized worldwide for its unique WORLD LEADING USA IMPORTED POLYURETHANE, HIGH PRESSURE, BONDING CRAFT Technology, as well as HIGH PRESSURE FORGING, INVESTMENT CASTING, WORLD TOP CLASS HEAT TREATMENT, FRICTION WELDING & PRECISE MACHINING Technology and high quality products in the O&G industry, by designing and fabricating HNA Bottom Guide Valve Body -- Two-Pieces Welded with Bonded Polyurethane for Duplex, Triplex and Quintuplex pumps, which are 100% interchangeable to most of the global famous brands: Bomco, Honghua, TSC, Weatherford, Ellis Williams, Gardner Denver, Emsco , National, Oilwell, Ideco, Drillmec & other major types of models, and customized design and production available.

Features:   

* HNA is the first manufacturer in China designs and fabricates the polyurethane bonded valve for American customers since 2009

* High Pressure Forged valve body and Investment Cast  bottom guide (valve leg/wing) 

  AISI 8620(20CrNiMo)

 (Or customized material)

* World Top Class Heat Treatment ensuring best mechanical properties (Tensile, Yield, Charpy Impact, Elongation etc) and Temperature & Corrosion Resistance Performance Exceeding API Standard for extended service life  

* World Top Class Friction Welded Technology & Precise Machining Crafts offer high precision machined components for a close tolerance fit

* 4-Wing, 3-Wing and custom designed bottom guide valve body is available to matching with 4 web, 3 web and full open valve seat. When pumping abrasive mud liquid, the tapered bottom guide legs allow greater flow area and reduced fluid velocity to form smoother flow, and therefore reduce abrasion and extend the valve service life. Valve with tapered bottom guide legs design is more suitable for high pumping speeds.

* Precisely tapered & balanced design of the bottom guide provides uniform loading characteristics and therefore ensures better sealing performance

* Two pieces welded design

* Bonded Valve Type Benefits:

1)Increased structural strength with very high tensile strength for longer operation life,

2)Improved shock absorption and minimized shock when valve closes,

3)Enhanced sealing capabilities and sealing failure prevention via Reduced possibility for fluids to penetrate between the polyurethane insert and the valve body

* USA Imported High Performance Polyurethane with:

  High Extrusion/Abrasion Resistance:Extremely Perfect

  High Chemical/Corrosion Resistance: Extremely Perfect

  High Pressure Resistance: Maximum 7,500 Psi  

* Regular Temperature220F(105C)(Yellow) and High Temperature 300F(150C)(White) Polyurethane valve insert for options

* Precisely tapered design of the insert matching with the seat provides evenly distributed loading characteristics and therefore ensures better sealing performance.Double angle 55°, 45°, or other specified taper design available to match with different valve type, pump type and applications.

* Compatible with API Valve Seat and Non-API Modified Valve Seat. While matching with HNA valve seat, it provides maximum fluid flow and longer service life because of the large metal-to-metal bearing area on the valve seat surface

* Shelf Life: Perfect (<36 months, under proper storage condition)

* Extremely Long Service Life Exceeding API Standard

* Domestic High Quality Polyurethane & USA High Performance Polyurethane for Options

* Fully interchangeable with Roughneck，SWND Bonded Valve, and other major valve types,available in API 3# thru API 9# sizes, and Non-API Modified Type & Sizes 

* Customized bonded NBR/HNBR Rubber as options
