his valve is generally used for reducing the high pressure air and high pressure gas

详细描述

■ FEATURES

This valve is generally used for reducing the high pressure air and high pressure gas.
1. Its construction is direct acting type and is not needed an auxiliary equipment such as an electric and a compressed air.
2. When the changing the primary pressure, its associating secondary pressure can be adjusted less than ±8% range.
3. Its setting pressure can be adjusted easily by using the upper handle.
4. Its small diameter can allow high primary pressure to be reduced very much.
