Product information Questions
- Tell me the difference among the full bore type, standard bore type and reduced bore type?
-
The bore types are classified as follows:
・ Full bore type: This type refers to a structure with which the inner diameter of the flow path becomes the same as the inner diameter of the pipe when the valve is fully opened and no resistance is added to the fluid.
・Reduced bore type: This type refers to a ball valve whose ball inner diameter is one size or more smaller than the nominal diameter of the valve.
・Standard bore type: This type refers to a ball valve whose bore diameter is one size smaller than the nominal diameter of the valve.
- What does the casted “S” on a cast iron valve mean? (Example: “S” of “10K-150S”)
-
The casted “S” on the cast iron valve indicates that the seat structure of the disc is a threaded type.
- Tell me how to read the product code (FIG).
-
For how to read the product code, please check “Overview of KITZ Product Code System” in the general catalog digest version.
- Is it possible to get 3D CAD data?
-
We do not provide 3D CAD data, but we plan to prepare BIM data in the future.
- What are the differences between 10UTB and 10UTDZ?
-
The main structural differences between 10UTB and 10UTDZ are as follows.
- Tell me the difference between the aluminum butterfly valves for hot water supply and water supply.
-
The seat rubber is different for hot water supply and water supply.
We recommend the butterfly valve with EPDM seat for water supply when using it for water supply piping and that with FKM seat for hot water supply when using it for hot water supply piping.
- What are the selection criteria for standard, high torque spring, and low torque spring of wafer type check valves?
-
Please refer to the following criteria as a guide when selecting the standard torque spring, low torque spring or high torque spring for the spring to be attached to the disc of a wafer type check valve.
- Tell me the opening at the time of shipment from the factory of pneumatic automatic ball valves.
-
Basically, double-acting types (B type / FA type) are shipped at the fully open position and the single-acting types (BS type / FAS type) are shipped with airless.
However, this is not the case when ancillary equipment is equipped with.
- Tell me the opening at the time of shipment from the factory of electric automatic ball valves.
-
For electric ball valves, the 2-way valves are shipped at the fully open position and the 3-way valves are shipped at the rotation stop position in the counterclockwise rotation.
