Качество и стандарты
YXCHK manufactures all 4WEH16 valves in our Zhejiang factory (est. 1994) with 48 CNC machines and an annual output of 80,000+ sets. Each unit passes a 100% factory test covering electrical continuity, internal leakage and maximum working pressure, and is Intertek-certified for high-pressure reliability.
Mounting patterns follow the international ISO 4401 / DIN 24340 standard, dimensionally matching Bosch Rexroth and Yuken original series. Valves are backed by a 1-year replacement warranty and an 8-year design service life in standard industrial environments.
Часто задаваемые вопросы
Is the 4WEH16 series 100% interchangeable with the original Rexroth 4WEH16 series?
Yes. YXCHK 4WEH16 valves use the identical mounting pattern (NG16 / Cetop 7 / ISO 4401-07), electrical interface and performance data as the original Rexroth 4WEH16 series, so they drop into existing manifolds and systems without any modification, re-piping or redesign.
What is the maximum working pressure and flow of the 4WEH16 series?
The 4WEH16 series is rated at 31.5 MPa maximum working pressure with a maximum flow of 300 L/min. T-port back pressure is limited to 16 MPa.
Which coil voltages are available for 4WEH16 valves?
DC 24V, AC 220V. Standard connectors are compatible with DIN 43650 / ISO 4400 plugs, and all coils are wet-type solenoid designs for extended service life.
What warranty and quality testing apply to 4WEH16 valves?
Every valve is 100% factory tested (electrical continuity, internal leakage and max pressure) before shipment, Intertek-certified, and covered by a 1-year replacement warranty with 24/7 engineering support.
