Cast iron gate valve specifications

Cast iron flanged gate valve is notable for its good flow resistance. It is operated with a handwheel, if manually actuated.

This element of water supply systems is widely used and is designed for pipelines with nominal inside diameters of 5 cm to 3 m. Its distinctive features are simple design and low flow resistance.

Cast iron flanged gate valve is notable for its good flow resistance. If manually actuated, it is operated with a handwheel which moves the members together until the body clearance is completely shut off.

Depending on the configuration, the following gate valve types are distinguished:

• full shut-off valve;
• reduced gate valve.

The first option has a larger diameter than the second option. The difference consists in a lower flow resistance. Therefore, reduced products are mainly used in systems where liquids are transported at fixed velocities.

The rising spindle is an important feature of the cast iron flanged gate valve. It facilitates maintenance by providing easy access to structural elements.

The system without the rising spindle also has certain benefits. For example, if the operating area must be designed small-sized, this part occupies one and a half times less space than the previously mentioned part.
