A rubber-lined wedge gate valve is one of the most common types of shut-off valves used to completely shut off the flow of the working medium in pipe systems. The F4 GGG50 + EPDM PN16 model from UKSPAR combines high quality, durability and maintainability.
This shut-off valve provides a hermetic flow shut-off thanks to a rubber wedge that fits snugly against the seat. Its body is made of cast iron, with a wear-resistant epoxy coating, which increases the corrosion resistance of the product. This pipeline valve is designed for air or drinking water, it is widely used.
Cast iron gate valve with rubberized flange wedge is manufactured in accordance with strict international standards. Main technical characteristics of the product:
Such parameters ensure high reliability, maintainable design and long service life of the Z101 valve even under intensive operation.
Such flanged valves structurally consist of several elements:

This rubber-coated flanged wedge gate valve has a flange mounting, which makes it easier to install and remove in any pipeline system.
Information is printed on the valve body that allows you to determine its main parameters:
This marking ensures product identification during installation, maintenance or replacement.
To ensure that a cast iron valve with a rubber-coated wedge works for a long time and efficiently, it is important to perform scheduled inspections:
The repairable design allows for easy replacement of worn elements without dismantling the entire valve, which reduces maintenance costs.
During operation, typical deviations in operation sometimes occur, which can be dealt with independently or with the help of service.
| Malfunction | Possible cause | Solution |
| The tightness of the parallel double-disc valve is broken. | Not completely closed passage | Apply the calculated force to the flywheel |
| Damaged or worn sealing surfaces | Grind or repair the defect | |
| Leakage through gasketed joints | Insufficient gasket seal or loose screw tension | Tighten the screws evenly. |
| The gasket was worn out. | Replace | |
| The seal is permeable to the working medium (air/water) | Insufficient packing seal | Tighten the gland bolts. |
| Packing wear | Add more gaskets or replace with new ones |
Regularly checking the locking mechanism and rubber seal helps to avoid leaks and extend the life of the product.
Installation of such pipe valves is performed in a horizontal or vertical position. It is important to ensure the alignment of the flange connection and to avoid mechanical stresses in the pipeline.
Basic installation requirements:
Compliance with these requirements guarantees hermetic sealing and stable operation of the valves even in difficult operating conditions.
