1. Characteristics
Wedge gate valves are designed for general use pipelines in industrial systems, for the second group of fluids. They are designed to cut off the flow of industrial water, drinking water, steam, air. They are also used in chemical industry (for non aggressive and non toxic liquid and gas substances), petrochemical and refinery industries, coke and chemistry industry (coke-oven gas), extractive industry, mining industry, mining and metallurgical industry (post-floatation wastes). They can be installed on pipelines in a vertical or horizontal and operating only when fully open or closed.

4. Directions for ordering
When giving your order you should supply the following information:
Steam tracers The Central European climate imposes special requirements concerning the protection of industrial transferring appliances In chemical plants, refineries, petrochemical and other plants in order to protect them from low temperatures. This kind of protection is guaranteed by steam tracing system, which is based on the trace lines.
Inverted bucket steam traps The WZ steam traps are inverted bucket steam traps. They operate thanks to difference in displacement of the float which is filled with condensate or a mixture of steam and water.
Wedge gate valves Wedge gate valves Gate valves are designed for general use pipelines in industrial systems. They can be installed on pipelines In a vertical or horizontal position and operate only when fully open or closed. Medium can flow in both directions. Typically we produce gate valves with hand drive.
