Dry Disconnect

OPW Drylok™

OPW Drylok™

OPW®, U.S.A.

DrylokTM is designed to safely transfer hazardous corrosive, volatile liquids such as acids, solvents and petrochemicals. An interlocking handle averts accidental spills by preventing uncoupling while the valve is open. And, the unit's flat face minimises fluid loss, further reducing exposure to risk during operation. DrylokTM is ideal for all kinds of hazardous fluids where product loss is a problem, such as high-pressure lines, high flow rates, slurries and gases.

- Driest disconnect in the industry - less than 1/2 ml of fluid loss from a 2" unit.
- Meets or exceeds requirements set by EPA, OSHA, and others. DrylokTM cannot be uncoupled while the valve is open.
- Optimum flow rate - less obstruction in easy-flow interior optimises the flow rate in high-pressure or high-viscosity applications.
- Easy of use - simple lever action connects valve to coupler and opens and closes the flow. 360o orientation ensures proper seating and alignment. No clamps, clips, loops or tabs that can cause operator error.

- Available in 1", 2" and 3" sizes.
- Standard O-ring seals for longevity and economy.
- Adjustable packing nut with V-type material provides a continuous compression, emission-free seal on handle shaft (2" & 3" only).
- Available in 316 Stainless Steel, Alloy 20 or Hastelloy® C with NPT, BSP, ASME Flanged, BW, and SW end connections.
- AAR Approved.
- CRN Approved.
