Valves that have not been actuated for a period of time may require a higher cracking pressure than the set cracking pressure.

Slotted handle : allows low setting adjustment with a screwdriver. and Handle stop : mechanically helps prevent damage to stem and orice.

DK-Lok Gap gauge allows easy inspection for sufficient tube pull-up before a system is pressurized. and Pressure rating up to 5,000psig (345bar) @100°F (38°C).

Isolated threads located above bonnet O-ring prevents media contamination and thread lubricant washout. and Straight-through orice hence roddable for easy cleaning.

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.

The valve ensures positive and consistent shut-oò with manual and oòers a metal to metal seal to atmosphere for leak integrity with thin plate diaphragm.

Traps fine contamination to maintain system purity, Choice of reliable DK-Lok, NPT & ISO pipe end connections. and Standard micron filtering ranges.

It’s integrally one-piece double block & bleed assemblies, for primary isolation of pressure take-offs, where the valve is directly mounted to the vessel or process pipe.

Blow-out proof design with internally loaded stem further Floating Ball design providing seat wear compensation and high integrity.
