Precision and Power: Introducing the GS-1200 Engine Valve Guide Removal and Installation Machine
In the world of engine rebuilding, precision and hydraulic power are paramount. Whether you are dealing with passenger cars or heavy-duty truck engines, removing and installing valve guides requires a machine that combines force with accuracy. Today, we are proud to introduce the GS-1200, a hydraulic powerhouse designed to streamline your cylinder head service workflow.
Why the GS-1200 Stands OutThe GS-1200 is engineered to handle a wide variety of cylinder heads, offering a robust solution for workshops aiming to increase productivity. Here is why this machine is a game-changer:
Immense Hydraulic Power: With a working pressure of 200 bar and an adjustable pressure range of 0–250 bar, the GS-1200 delivers a press force of up to 16 tons. This ensures that even the most stubborn, seized valve guides can be removed without damaging the cylinder head.
Versatile Handling: The machine accommodates cylinder heads with dimensions up to 1350 mm in length and 415 mm in width. This makes it suitable for everything from compact car engines to large industrial diesel engines.
Ergonomic Design: The worktable features a 50° rotation, allowing the operator to position the cylinder head at the optimal angle for visibility and access.
Precise Control: With a rod speed of 28 mm/min and adjustable upper/lower piston travel, operators maintain full control over the installation depth, ensuring OEM-level precision.

For those interested in the numbers, here are the detailed parameters of the GS-1200:
| Feature | Specification |
| Max Press Force | 0–16 ton |
| Max Cylinder Head Size | 1350 mm (L) x 415 mm (W) |
| Travel Range | Vertical: 150 mm |
| Table Rotation | 50° |
| Working Pressure | 200 bar (Adjustable 0–250 bar) |
| Motor Power | 0.75 kW |
| Dimensions | 1550 x 900 x 1980 mm |
| Power Supply | 3×400V or 3×230V (50/60Hz) |
| Net Weight | 445 kg (981 lbs) |
Weighing in at 445 kg, the GS-1200 is a solid, vibration-free platform. Its rigid construction ensures longevity even in high-volume engine machine shops.
Application Scenarios
Heavy-Duty Truck Repair:
Thanks to its 1350 mm length capacity and 16-ton force, the GS-1200 is perfect for servicing long cylinder heads found in commercial trucks and buses.
Marine Engine Maintenance:
Ideal for removing bronze or cast-iron guides in medium-sized marine diesel engines where high extraction force is required.
Automotive Machine Shops:
A universal solution for general automotive engine rebuilding, handling multi-valve cylinder heads with ease due to the 50° tilting table.
Construction & Mining Machinery:
Capable of servicing the rugged engines found in excavators and bulldozers.
Q1: What is the maximum size of cylinder heads the GS-1200 can handle?
A: The GS-1200 can accommodate cylinder heads up to 1350 mm (53 inches) in length and 415 mm (16 inches) in width.
Q2: Can I adjust the pressing force to avoid damaging delicate cylinder heads?
A: Yes, the pressure is fully adjustable from 0 to 250 bar (0–16 tons), allowing you to set the precise force needed for different materials and guide sizes.
Q3: What power supply is required for this machine?
A: The machine is versatile and can be configured for 1.6kVA, 3×400V AC + PE 50/60Hz or 1.6kVA, 3×230V AC + PE 50/60Hz, depending on your region's voltage standards.
Q4: Does the machine come with hydraulic oil?
A: The machine has a tank capacity of 7 Liters. Please check with our sales team regarding shipping regulations for hydraulic fluids.
Q5: How does the tilting table help the operation?
A: The table rotates up to 50°, which allows the operator to align the valve guide axis perfectly with the ram, ensuring straight installation and preventing side-loading damage.
