Product Overview
The Vaner body (valve body) of the mud pump/fracturing pump is a key high-frequency moving sealing component in the valve box of the liquid cylinder. It works in conjunction with the Vaner seat and Vaner rubber to achieve high-pressure suction and discharge of the pumped medium. The van der body produced by our company is forged from high-quality 20CrMnTi/8620H high-strength alloy steel, and undergoes carburizing and quenching heat treatment. The guide legs and sealing conical surfaces are precisely ground, featuring extremely high mechanical strength, high-pressure impact resistance and wear resistance, which can meet the requirements of high-pressure and high-flow drilling and fracturing operations.

Performance features and advantages |
Four or three tendons guide the Van der body
(Webbed Valve Body) |
20CrMnTi high-quality alloy steel
Integral forging + carburizing and quenching |
API 4# ~ 8#
(Such as API 4#, 5#, 6#) |
≤ 34.5 MPa
(5000 PSI) |
Water-based and oil-based mud
≤ 80℃ |
The multi-rib structure ensures smooth guidance, precise positioning, uniform force distribution, and high cost performance. It is widely used in conventional oil and gas drilling mud pumps. |
Through-hole ribbed Vernier body
(Full Open Valve Body) |
High-quality 8620H / 20CrMnTi
Precision forging + hardening heat treatment |
API 4# ~ 8#
(API-4, API-5, API-6) |
≤ 52.0 MPa
(7500 PSI) |
High sand content/high viscosity slurry
≤ 110℃ |
The absence of intermediate ribs for flow resistance effectively reduces medium erosion and flow resistance, significantly extending the service life under high-flow and high-pressure conditions. |
Double-guided/top-guided Van der body
(Top & Bottom Guided) |
High-strength alloy steel
Surface carburizing and polishing treatment |
API 5# ~ 7# |
≤ 37.0 MPa
(5360 PSI) |
Common water-based/oil-based mud
≤ 90℃ |
The upper and lower dual guidance prevents uneven wear. The opening and closing process of the switch is smooth without skew, which can significantly protect the sealing conical surface of the valve seat. |
High-temperature resistant/anti-corrosion fracturing vernier
(High-Temp / Acid Resistant) |
Corrosion-resistant alloy steel
Special surface blackening/anti-corrosion coating |
API 4# ~ 8# |
≤ 103.5 MPa
(15000 PSI) |
Strong acidity (containing H2S/CO2)
Fracturing proppant medium, ≤ 150℃ |
Designed for deep well extremely high pressure and strong corrosive fracturing conditions, it has extremely strong resistance to fatigue cracking, cavitation and acid and alkali erosion. |
Compatible pump type
Compatible with mainstream mud pump and fracturing pump brands F-500, F-800, F-1000, F-1300, F-1600, FB-1300, FB-1600, 3NB-500, 3NB-800, 3NB-1000, 3NB-1300, PZ-7/8/9/10/11, TWS 600, SPM 2250, etc.
Ordering Instructions
When placing an order, please specify the pump type and API number (such as API 6# or API 7#).
2. Please confirm the style of the Vail body (with foot ribs or through holes without ribs) to prepare the matching Vail seat and rubber combination.
