Dry Disconnects
SYSTEM COMPONENTS
OPW Engineered Systems’ dry-disconnect couplings prevent spillage from both routine and accidental disconnects.
A dry disconnect consists of a built-in valve and a spring-loaded poppet in the mating adaptor that automatically
closes when disconnected. OPW's line of dry disconnect products include Drylok™ and the economical Kamvalok®
Both Drylok™ and Kamvalok® are suitable for a wide range of hazardous transfer applications.
Drylokc
Drylok™is designed to transfer
hazardous, corrosive, volatile liquids
safely. 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.
Benefits
o Driest disconnect in the industry - less than 1-cc of fluid loss
from a 3" unit.
¢ Unprecedented safety — meets or exceeds all of today’s
stringent emission and worker safety requirements set by
EPA, OSHA and others. Drylok™cannot be uncoupled while
the valve is open.
¢ High-pressure line applications — rated at 300 psi in the open
and flowing position.
¢ Can be opened and closed against 150 psi maximum
head pressure.
¢ Optimum flow rate — unique design optimizes the flow rate
in high-pressure or high-viscosity applications.
Features
® 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
* Available in 316 Stainless Steel, Alloy 20° or Hastelloy® C with
NPT, BSP, ASME Flanged, BW and SW end connections
* AAR Approved and CRN Approved.
Vacuum
Breakers
OPW Engineered Systems’ Vacuum
Breakers for high-pressure
applications permit quick, positive
evacuation of the arm after the
loading operation is complete.
The 476SA model is available in
aluminum with stainless-steel
internal parts. The 489 model is
stainless-steel for severe
applications and tough liquids.

Kamvalok®
OPW Kamvalok® Dry
Disconnect Couplings, the
industry standard, are used at
liquid transfer points where
product loss could occur. OPW
Kamvaloks® provide a reliable
solution to prevent spillage
during connection or disconnection.

OPW Kamvalok® Dry Disconnect Couplings are used by
a wide range of manufacturing applications including
petroleum products, solvents, Ag-chemicals, vegetable oils,
detergents and many acids and caustics.
Benefits
* Spill Protection — helps to reduce the hazards involved
in the connection/disconnection process of transferring
materials.
* Provides For Total Closed-Loop Loading Capabilities —
when used with the OPW 2173N Vapor Recovery Dry
Disconnect Coupling protects people and property
from dangerous and potentially costly exposure by
keeping hazardous liquids and vapors in-line.
* Dual Protection — OPW Kamvaloks® provide
automatic closure from both directions — the coupler
and the adaptor.

Loading Valves
OPW Engineered Systems' Loading Valves are designed
to shut off flow without causing damaging shock in the
pipeline. Pipeline shock, or “hammer,” causes problems
with pipe joints and instruments in the line. Fast,
shockless closing is assured by use of an adjustable needle
valve and a dashpot. Air cannot be trapped in the valve,
and as a result, the valve does not open after closure.
This variable closure rate controls shock with minimum
afterflow. Loading valves are available in several styles.
