Introduction of mud pump cylinder liner manufacturers Since 2009, HNA has been famous for its professional engineering design and production technology, as well as excellent product quality in the oil and gas field. It specializes in the introduction and development of three-cylinder and five-cylinder plungers. The pump is imported from the United States with polyurethane, high pressure and vulcanization integrated process technology and products, and adopts exquisite high pressure forging, precision casting, heat treatment technology, friction welding and finishing technology to design and produce HNA valve claw welding valve body - vulcanization integrated Type polyurethane valve rubber, which can be interchanged with products of major well-known brands, such as Halliburton, Weir SPM, Gardner Denver, Oilwell, FMC, OFM, Cooper OPI, SJ, Serva, JR, SANY, etc., and can be customized according to customer's special requirements Request for customization.

Features:

* HNA is the first manufacturer in China to design and produce vulcanized one-piece polyurethane rubber valve body for American users, started in 2009

* High pressure forged and precision cast body and jaws

AISI 8620(20CrNiMo) AISI 8620H(20CrNiMoH) Material

 (or customer specified material)

* Exquisite heat treatment equipment, process and carburizing technology ensure excellent mechanical properties of valve body and claw (tensile, yield, impact energy, elongation, etc., surface hardness can reach 60--65HRC), as well as high temperature resistance and corrosion resistance Performance, higher than the API standard requirements, greatly extending the service life

* Exquisite friction welding and finishing equipment and process manufacturing valve body, high precision, small tolerance, tight fit

* HNA valve is designed and manufactured according to API standard requirements, suitable for various cementing and fracturing media, such as sand proppant, synthetic resin-coated sand proppant, etc. The superior performance of the valve body allows it to perform well in the most severe service environments, such as stable pumping of ceramic proppants or sintering at high pressures in excess of 1,000 SPM (strokes per minute) and 15,000 Psi Liquid flow of bauxite proppant. A variety of different rubber or polyurethane rubbers are available for different working conditions

* Claw body type, 4-claw, 3-claw, or customized design, can be used with through hole seat. In the condition of mud containing abrasive impurities, the taper claw shape design can provide a larger flow area, reduce the flow rate, and guide the formation of a smoother flow, thereby reducing wear and extending the service life of the valve body. Tapered claw body design is more suitable for high pump speed conditions.

* Tapered, highly balanced jaw design provides balanced load carrying capacity for improved sealing performance

* Welded 2 piece design

* Advantages of vulcanized one-piece body:

1) The overall structural strength is improved, the tensile strength is higher, and the service life is longer,

2) When the valve body is closed, the shock absorption and shock absorption capacity are improved,

3) Greatly reduces the possibility of drilling fluid penetrating into the gap between the rubber and the valve body, thereby improving the sealing performance and effectively preventing seal failure

* Performance of high-performance polyurethane rubber imported from the United States:

High crush/wear resistance: very good

High corrosion resistance: particularly excellent

High pressure performance: maximum working pressure 15000 Psi

* Normal temperature 220F (105C) (yellow), high temperature 300F (150C) (white), 2 kinds of polyurethane valve rubber optional

* The cooperation between the rubber and the valve seat adopts a precise taper angle design, which can provide a more balanced bearing capacity, thereby improving the sealing performance. Double angle 55°, 45°, or other tapers to match different body seats, pump types and applications

* Can be used with API standard valve seat and non-API standard modified valve seat. Larger area metal-to-metal seat bearing surface provides maximum flow and longer life when used with HNA seats

* Shelf life: Excellent (<36 months under proper storage conditions)

* Long product life, higher than API standard requirements

* High-quality polyurethane rubber made in China, high-performance polyurethane rubber made in the United States, 2 options are available

* The product is completely interchangeable with the SPM 2.0 valve body, as well as the valve body of the world's major brand pumps. Size specifications: API 3# -- API 9#, and non-API standard improved specifications and sizes

* Customized vulcanized one-piece NBR/HNBR valve body
