HAITIAN SOLENOID OPERATED DIRECTIONAL VALVE
Model: SWH‑G02‑C22‑D24‑20‑M3
Product Overview
SWH‑G02‑C22‑D24‑20‑M3 is a high‑performance solenoid operated Hydraulic valve, specially optimized for Haitian injection molding Machine. As a core flow‑switching component in the hydraulic system, this Hydraulic valve controls the direction of hydraulic oil flow to realize the actions of clamping, injection, ejection and mould‑opening of injection‑molding equipment. The M3 version is dedicated for plastic‑machinery working conditions, featuring shock‑absorbing performance to reduce hydraulic impact during spool switching. With 24VDC solenoid coil, plate‑mounted installation structure and C22 spool function, it can accurately switch oil circuit status according to electrical signals. Reliable performance of this Hydraulic valve ensures stable logic execution of the whole hydraulic system and normal cyclic operation of the injection molding Machine. It is widely used for original equipment matching, on‑site overhaul and aftermarket spare‑parts replacement of Haitian injection‑molding machines.

Working Principle
When the 24VDC solenoid receives electrical control signals, electromagnetic force pushes the internal spool of the Hydraulic valve to shift, changing the connection status of each oil port. It switches the flow direction of pressure oil inside the hydraulic system, driving hydraulic cylinders and actuators to complete different mechanical movements. After power‑off, the reset spring pushes the spool back to neutral position. The built‑in M3 shock‑absorbing structure effectively relieves pressure spike when spool reverses, reducing vibration and noise of the Machine. If the spool is stuck or seals wear, faults such as action delay, unstable mould‑clamping, internal leakage and abnormal noise will occur. Replacing the qualified directional valve can restore normal oil‑circuit switching function and keep the hydraulic system running steadily.
Core Advantages
1. M3 special shock‑absorbing design for plastic machinery, effectively reduces hydraulic impact when the Hydraulic valve switches, lowers vibration and extends component service life of the injection molding Machine.
2. High‑precision spool‑valve matching, sensitive response, adapts to high‑frequency cyclic actions of injection‑molding hydraulic system.
3. Heavy‑duty sealing components, strong oil‑pollution resistance, suitable for long‑time continuous production environment of injection‑molding workshops.
4. Standard G02 plate‑mount dimension, easy installation and replacement, no modification required for original manifold of Haitian equipment.
5. Strict quality control, stable pressure‑bearing performance, reduces downtime caused by valve failure and improves production continuity.
Application Range
SWH‑G02‑C22‑D24‑20‑M3 solenoid directional Hydraulic valve is a key control component for the hydraulic system of Haitian injection molding Machine. Mainly used for injection‑molding machine clamping unit, injection unit and ejection circuit control. Suitable for plastic‑product manufacturers, equipment maintenance workshops and hydraulic‑system service providers for spare‑parts stock and machine overhaul.
