產品詳細

First, the main technical performance indicators

Leakage rate: single seat valve, small flow valve is less than the rated capacity of the valve 10-4

Double-seat valve, less than the rated capacity of the valve 5 × 10-3

Back to the difference: with locator, less than 3% of the full stroke

Basic error: with locator, less than ± 3 full stroke

Note: The standard V-type PTFE packing.
