Precision flow control for demanding applications – The OEM W8605051100012 Three-Way Ball Valve (2 1/2″, DN70) is engineered to provide reliable, leak‑tight switching between fluid circuits in heavy‑duty trucks and industrial equipment. Designed for extreme operating conditions, this valve ensures smooth actuation and long service life. For guaranteed compatibility and performance, always choose genuine Sinotruk Homan parts. The three‑way ball valve design offers low flow resistance and positive shut‑off, ideal for hydraulic oil, coolant, fuel, and air distribution systems in construction, mining, and transportation fleets.
The W8605051100012 three‑way ball valve features a full‑bore design that minimizes pressure drop and allows high flow rates. The chrome‑plated ball and PTFE seats provide excellent sealing even after thousands of cycles. This valve is ideal for diverting or mixing media in hydraulic circuits, fuel systems, and cooling loops. Its robust carbon steel body with epoxy coating resists corrosion and withstands harsh environments. The valve’s compact size and standardized port connections make it a direct replacement for many OEM applications.
L‑port or T‑port configurations available. The W8605051100012 can be used for diverting flow from one inlet to two outlets or mixing two inlets to one outlet.
Carbon steel body (WCB), stainless steel ball, PTFE seats. Rated for pressures up to 40 bar and temperatures from -20°C to +180°C, suitable for oils, fuels, water, and air.
Zero leakage across the seat and stem (tested at 1.1× rated pressure). 90° lever handle provides clear position indication.

The W8605051100012 three‑way ball valve is manufactured using precision investment casting for the body and stem. The ball is ground to a mirror finish to ensure smooth operation and tight sealing. Primary sealing is achieved by pre‑loaded PTFE seats with a secondary metal‑to‑metal backup, providing fire‑safe design per API 607. The stem is blowout‑proof and equipped with anti‑static devices to prevent spark generation. Every valve is hydrostatically tested at 1.5× rated pressure and seat leakage tested at 1.1× rated pressure to guarantee zero detectable leakage.
The W8605051100012 is compatible with hydraulic oils (mineral and synthetic), diesel fuel, biodiesel, engine coolant, compressed air, and water. PTFE seats resist almost all chemicals, while the carbon steel body is protected by a high‑build epoxy coating suitable for outdoor and corrosive environments. For more aggressive media or higher temperatures, optional seat materials (PEEK, Devlon) are available upon request.
The W8605051100012 valve comes standard with a lever handle for manual operation, providing clear visual indication of flow direction (L‑port pattern). The ISO 5211 top flange (F07/F10) allows easy mounting of pneumatic or electric actuators for remote control. SINOTRUK Homan can supply pre‑assembled actuated valve kits with positioners and limit switches, simplifying automation integration in fleet fueling stations or industrial processes.
For correct installation of the W8605051100012, follow these steps: 1) Ensure pipeline is clean and free of debris. 2) Apply thread sealant (PTFE tape or pipe dope) to male threads only – do not overtighten; maximum torque 180 Nm. 3) Mount the valve with the handle in the desired orientation; ensure the valve is fully open or closed during installation. 4) For L‑port configuration, verify flow pattern (common inlet at port 2). 5) After installation, cycle the valve several times to check smooth operation. 6) Test for leaks at system pressure before putting into service.
The W8605051100012 requires minimal maintenance. Annually inspect the stem seal for leakage and tighten the stem nut if necessary. If the valve becomes difficult to operate, disassemble (following factory instructions) and clean the ball and seats with a mild solvent. Do not use abrasive tools. Replace seats every 50,000 cycles or when leakage exceeds allowable limits. Always use genuine SINOTRUK Homan repair kits to maintain fire‑safe certification.
The W8605051100012 three‑way ball valve is manufactured under ISO 9001:2015, PED 2014/68/EU (CE marked), and API 608. Each valve is 100% tested: shell test at 1.5× PN for 60 seconds, and seat test at 1.1× PN for 30 seconds with zero leakage allowed. The valve also passes a low‑pressure air test at 6 bar for seat integrity. Fire‑safe design is validated per API 607 7th edition. A test certificate with unique serial number is included.
A field study on 120 heavy trucks equipped with the W8605051100012 valve for hydraulic oil diversion showed zero leaks after 18 months of operation in construction environments. A mining company replaced competitor valves with this model and reported a 60% reduction in downtime due to valve failures. In fuel distribution systems, the valve’s low operating torque and clear position indication improved operator safety and efficiency. These results confirm the superior design and materials used in the W8605051100012.
Each W8605051100012 three‑way ball valve is supplied in a heavy‑duty carton with foam inserts, including the valve, lever handle, and installation manual. A laser‑etched serial number and QR code are applied to the body. Scanning the QR code redirects to the SINOTRUK Homan verification portal, confirming authenticity. Counterfeit valves often have inconsistent markings, poor surface finish, and lack fire‑safe documentation. Always purchase from authorized distributors.
Summary: The SINOTRUK Homan Three‑Way Ball Valve (OEM W8605051100012, 2 1/2″ DN70) offers reliable flow control, leak‑tight sealing, and long service life. Upgrade your fluid handling system with this genuine OEM component, trusted by professionals worldwide.
