Features:   

* High Pressure Forged One-Piece integral valve seat 

  AISI 8620(20CrNiMo) AISI 8620H(20CrNiMoH) AISI 4119(20CrMnMo)

(Or customized material)

* World Top Class Heat Treatment & Carburizing Technology ensuring best mechanical properties (Tensile, Yield, Charpy Impact, Elongation etc, with surface hardness 60-65 HRC) and Temperature & Corrosion Resistance Performance Exceeding API Standard for extended service life  

* World Top Class Precise Machining Crafts offer high precision machined components for a close tolerance fit. Special care is taken for the dimensional matching of the valve seat and body working angle for ensuring longer service life even under extreme working conditions

* HNA’s valve seats are the API standard for cementing & fracturing media such as sand and man-made resin-coated sand proppants. The seat gives unparalleled performance in the most extreme conditions like pumping high-strength ceramic proppants or sintered bauxite proppants at pressures above 15,000 psi while withstands rates in excess of 1,000 SPM

* Full Open, Cage valve seat types specifically designed to match with Bottom Guide Type 4 Wing, 3 Wing, and custom designed valve body. 

* Precisely tapered design of the insert matching with the valve body 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.

* API Valve Seat and Non-API Modified Valve Seat Available. While matching with HNA valve, HNA Valve Seat offers large metal-to-metal bearing area surface, even loading of the seat deck in the fluid end module, and therefore promotes longer service life and maximum fluid flow

* High Extrusion/Abrasion Resistance:Extremely Perfect

 High Chemical/Corrosion Resistance: Extremely Perfect

  High Pressure Resistance: Maximum 15,000 Psi
