Check valves and gate valves

Zenit check valves are designed for use even with soiled liquids and provide full guarantees of operation even under heavy-duty working conditions.
The sinking ball system ensures a full free passage since at maximum opening the valve has a completely free main line, greatly reducing pressure drops. The capability for installation in a horizontal or vertical position provides greater versatility and optimal assembly.

Clapet valves can be used for non-abrasive clear wastewaters. Zenit models have body and disc in GJL-250 cast iron and brass and EPDM rubber seat. The lever which operates the mechanism is in GJS 400 cast iron for maximum reliability. Compliance with international design regulations simplifies installation and ensures compatibility with any standard flange.

The knife gate valves, with handwheel control, have various functions and are used as cut-off devices to regulate the flow in a pipeline or to temporarily isolate a section of the plant.
The gate valves have GJL-250 cast iron body containing the mechanisms used to partially or totally block the flow.
This product is designed to allow fitting of a servomotor for remote partial or total opening/closing (no manual operation required).

Zenit gate valves are in GJL-250 cast iron with the gate travelling in a brass seat to ensure smooth operation over time, even after long periods without use. Flanges meet the UNI standards for perfect interchangeability.
They are mainly used in distribution and treatment plants for civil and industrial wastewater in general.

VAP 32÷50

BALL CHECK VALVES

VAP ball check valves prevent backflow during plant maintenance or stoppages. They are designed for use even with soiled wastewaters to provide full guarantees of operation in heavy-duty working conditions.
The sinking ball system ensures a full free passage since at maximum opening the valve has a completely free main line, greatly reducing pressure drops.
They can be installed horizontal or vertical and do not require any maintenance.

The entire range of ball valves have "rubber on rubber" coupling (rubber ball; seal on rubber gaskets), guaranteeing quieter operation and easy restoration of perfect mating between the ball and the sealing lip.
