A valve is a device that regulates, directs or controls the flow of a fluid by opening, closing, or partially obstructing various passageways.
Valves are technically valves fittings, but are usually discussed as a separate category.
VBV
Spec.
ㆍWorking Pressure : 10,000 psig
ㆍHard chrome plate for extended service life and to improve seal-ability
ㆍStainless Steel and Carbon Steel
ㆍMale Pipe thread 1/8 to 1/2 in.
Brief Description
DK-Lok VBV Series Bleed Valves are designed to vent the signal line pressure to atmosphere before an instrument is removed and to assist in calibration of control
devices. These are for use on instrumentation devices such as gauge root valves and multi-valve manifolds. Optional barbed vent tube enables containment of fluid vented. The VBV Series are also ideal in bleeding hydraulic systems.
VPV
Spec.
ㆍWorking Pressure : 4,000 psig
ㆍFor bleeding, venting, and draning of system fluids.
ㆍStainless Steel and Brass
ㆍDK-Lok 1/8 to 1/2 in. OD
ㆍTube Adapter 1/4 to 1/2 in. OD
ㆍPipe thread 1/8 to 1/2 in.
