What This Machine Does
The TWS1100 is a cylinder head work station that holds the head where the operator needs it and does the valve assembly work at the same place. The table adjusts through 360 degrees and clamping is rapid and manually adjustable, so every face of the head can be reached without unbolting and rebuilding the setup. Valve work is handled by an air cylinder with variable speed regulation and a pneumatic foot control, which leaves both of the operator's hands free; a valve compressor lock holds the spring compressed so retainers and keepers come out hands free rather than being fished out under load. Five sizes of compressing foot cover different valve and retainer sizes, and valve keeper installing and retrieving tools are supplied with a polyethylene plate support to hold the valves in order. The TWB500 is the manual valve working bench version for shops that do not need the pneumatic station.
Why Buyers Choose This Machine
- 360 degree table adjustment gives access to every face of the cylinder head from one setup
- Valve compressor lock holds the spring so retainers are removed hands free
- Pneumatic foot control leaves both hands available for the keepers and retainers
- Variable speed regulation on the air cylinder lets the operator ease onto delicate springs
- Air cylinder tilts to any valve angle and the assembly slides from valve to valve
- Five sizes of compressing foot plus keeper installing and retrieving tools cover the whole head
- Camshaft setting and other head operations are done on the same station
Where Universal Workstation TWS1100 Earns Its Place
Problems It Solves
- Dropping a keeper back into the head under spring load costs minutes every valve
- A fixed bench forces the head to be unclamped and re-set for every face
- Hand spring compressors need both hands so there is none left for the keepers
- Angled valve banks cannot be compressed straight on a fixed vertical compressor
- A single size of compressing foot does not fit all valves and retainers on a mixed workload
- Loose valves get mixed up between cylinders during a strip
Who It Is For
- Cylinder head reconditioning shops
- Engine rebuilders stripping and assembling heads in volume
- Repair workshops doing occasional head overhauls on the TWB500
- Distributors equipping head shops in export markets
Application Scenarios
- Stripping valves springs and retainers from a cylinder head
- Reassembling valves and keepers after seat and guide work
- Camshaft setting on an overhead cam head
- Working angled valve banks where the air cylinder has to tilt to the valve axis
- General cylinder head bench work in a reconditioning line
- Manual valve bench work on the TWB500 where compressed air is not available

- Camshaft setting
Materials Handled
- Polyethylene
Quality Control
- Table rotation checked through the full 360 degrees with the clamp locked
- Air cylinder stroke and variable speed regulation tested across the range
- Valve compressor lock checked under spring load before shipment
- Compressing feet counted and checked against the five-size set
- Station assembled and function tested on a sample head before packing
Customisation Options
- TWS1100 or manual TWB500 chosen according to whether compressed air is available in your shop
- Compressing foot set matched to the valve and retainer sizes in your engines
- Clamping arrangement specified for the head types you handle
- Air supply fittings prepared for your workshop connection
- Manual prepared in your working language
How It Compares With the Alternatives
| Manual valve working bench TWB500 | The TWB500 does the same bench work by hand; the TWS1100 adds the pneumatic cylinder foot control and compressor lock, which is what speeds up volume head work |
|---|---|
| Hydraulic valve guide press machine TGP1200 | The TGP1200 exists to press interference-fit guides; the TWS1100 is the clamping and valve assembly station and does not replace the press |
| A hand-held spring compressor on a bench | A hand compressor takes both hands and cannot tilt to a valve angle; the TWS1100 holds the spring with a lock and tilts the cylinder to the valve axis |
Running the Machine
Step 1
Clamp the cylinder head on the table with the rapid manual clamping system
Step 2
Rotate the table to bring the valve bank you are working on to the operator
Step 3
Tilt the air cylinder to the valve angle and select the correct compressing foot from the five sizes
Step 4
Set the speed regulation so the cylinder eases onto the spring
Step 5
Use the foot control to compress the spring and the compressor lock to hold it
Step 6
Remove keepers with the retrieving tool and lay the valves in order on the polyethylene support plate
Step 7
Reverse the sequence on assembly using the keeper installing tool

Questions About Universal Workstation TWS1100
What is the difference between TWS1100 and TWB500?
The TWS1100 is the pneumatic universal work station with air cylinder foot control and 360 degree table. The TWB500 is the manual valve working bench. Choose the TWB500 if you do not have a compressed air supply.
Can it work on angled valve banks?
Yes. The air cylinder easily tilts to any valve angle and the assembly slides from valve to valve.
How many compressing feet are supplied?
Five sizes of compressing foot, along with valve keeper installing and retrieving tools.
Can I do camshaft work on the same station?
Yes. The station gives access for camshaft setting and all other cylinder head operations.
What air supply does the station need?
It runs on shop compressed air through a pneumatic foot control. Tell us your air supply and fittings and we will prepare the machine accordingly.
How is it packed and shipped?
Crated for sea freight with fumigated timber where required. Send us your destination port and we will quote FOB CFR or CIF.
What are your payment terms?
30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
