Drylok™ 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 minimizes fluid loss, further reducing exposure to risk during operation.

Drylok™ 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.

Features & Benefits
  • One of the driest dry-breaks in the industry – Less than 1/2 ml of fluid loss from a 2" unit (less than 0.10 of a teaspoon).
  • Super-Pak Adjustable packing with V-type material provides a continuous compression, emission-free seal on handle shaft (2”& 3” only).
  • Unprecedented safety – Meets or exceeds today's stringent emission and worker safety requirements.
  • Drylok™ cannot be uncoupled while the valve is open.
  • Optimum flow rate – less obstruction in easy-flow interior optimizes the flow rate in high-pressure or high-viscosity applications.
  • Ease of use – Simple handle action connects valve to coupler and opens and closes the flow.
  • 360° orientation ensures proper seating and alignment.
  • Simplicity of repair and maintenance.
