Q45 Solenoid Control Hydraulic Directional Valve Test: Precision Testing for Guaranteed Quality
In modern hydraulic systems, the performance of a hydraulic valve directly determines the overall efficiency and reliability of the equipment. To ensure every valve meets strict quality standards before delivery, hydraulic test benches play a crucial role in product validation.
The subject of this test is the Q45 solenoid-operated directional control valve, independently developed by BXHS Hydraulics. This product integrates high efficiency, versatility, and durability, making it ideal for a wide range of machinery and mobile equipment applications.
1. Purpose of the Test
The goal is to evaluate the Q45 valve’s performance through a series of critical inspections using a hydraulic test bench. The tests ensure the valve meets high standards of responsiveness, durability, and pressure stability in real-world conditions.
2. Key Test Parameters
Working Pressure Test
Measures the valve’s response and stability under its rated flow of 45 L/min and a maximum pressure of 315 bar (4600 psi).
Flow Performance Evaluation
Assesses the valve’s smooth shifting and precise flow control under variable flow rates to ensure optimal system performance.
Leakage Detection
Includes both internal and external leakage tests to ensure reliable sealing, preventing energy loss under high pressure.
Temperature & Thermal Stability
Evaluates the valve’s behavior during prolonged operation, ensuring it remains thermally stable and adaptable to various conditions.
Actuation and Stability Test
Repeated cycling and actuation testing to verify the responsiveness of the spool and durability of the solenoid mechanism.
3. Product Highlights
The Q45 valve features a robust cast iron body with a pull-type solenoid design. Key specifications include:
Rated Flow: 45 L/min (11.8 US gpm)
Maximum Pressure: 315 bar (4600 psi)
