Ball & Plug Valves

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

Check & Relief Valves

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

Metering & Bellow Valves

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

Needle & Regulator Valves

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).

Toogle & Rising Plug Valves

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

Bleed & Purge Valves

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.

Diaphragm & Gauge Valves / Manifolds

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.

Filters

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

Integral Block & Bleed Valve are integrally one-piece double block and bleed assemblies, for primary isolation of pressure take-offs, where the valve is directly mounted to the vessel or process pipe.
