Function & Operation
Model Y2/HB20B performs the manual directional control valve role in hydraulic circuits and is built as a direct, dimensionally identical replacement for the corresponding Shanghai H10B original. Set-point and porting behavior follow the original specification, so the valve drops into the existing manifold or line without re-engineering. Bodies are CNC-machined from high-grade cast iron to +/- 0.005 mm, with hardened internal components for long service.
Mounting & Electrical
Y2/HB20B matches the original mounting interface (ISO 4401 subplate, CETOP, or the Shanghai/Chinese standard H10B / H20B pattern for 24*/34* series) with identical bolt spacing and port positions. Solenoid-operated variants use a DIN 43650 connector rated IP65, with coil voltages DC 24 V and AC 220 V. Rated pressure is 31.5 MPa with max flow 80 L/min; fluid compatibility covers mineral oil HL/HLP per DIN 51524, and optional Viton seals are available for special fluids.
Quality & Reliability
Every Y2/HB20B unit is 100% factory-tested (electrical where applicable, leakage and peak pressure) with batch-archived records, holds Intertek certification, and is covered by a 1-year replacement warranty with an 8-year design service life. Standard orders ship within 7 working days from Ningbo Port with a 1-piece MOQ; OEM/ODM private labeling and customer-specified set points are available on request.
Where It Fits
Y2/HB20B serves machine tools, hydraulic power units, injection molding and general industrial hydraulics - wherever the system needs stable pressure control, directional logic or flow throttling. For a fast replacement, send the original model code and set-point details to our engineers; a cross-reference confirmation and quotation are provided within 24 hours, free of charge.
Typical Applications
- High-flow directional control
- Pilot-operated heavy machinery circuits
- Hydraulic press systems
Quality & Standards
Every YXCHK valve is 100% factory tested (electrical, leakage and max pressure) before shipment. Mounting patterns comply with ISO 4401 / DIN 24340 international standards, and the design follows the ISO 4401 hydraulic valve interface specification, matching the original Bosch Rexroth and Yuken dimensional standards.
Products are Intertek certified for high-pressure reliability, backed by a 1-year replacement warranty and 8-year design service life. Standard orders ship from Ningbo port within 7 working days.
