Product Description

Product introduction:

 Manual high vacuum butterfly valve allows the disc to rotate freely in the range of 90° to achieve the purpose of opening and closing or adjusting the medium flow. The valve plate of the valve adopts a clamping structure, and the sealing ring of the valve plate is clamped to play a better sealing role. The valve opening and closing have locking function.
The applicable working medium is air or non-corrosive gas.

Performance parameters:

Range of application (Pa)	10^5 to 1.3x10
Valve leakage rate (Pa.L/S)	< 1.3x10
Medium temperature (° C)	-25 ~ +80 (the sealing material is nitrile butadiene rubber) -30 ~ +150 (the sealing material is fluorine rubber)
Flanges standard	JB919
Mounting position	Any

Main Materials:

Body, cap, stem: carbon steel or stainless steel

seals: nitrile rubber, fluororubber.
