Camco B-1 Conventional Reverse Flow Check Valves

Features and Benefits •

Integral reverse check

•

Includes hard and soft seats

•

Available in standard or premium materials

Typical Applications •

Camco reverse flow check valves require flow to close. As the differential pressure across the valve’s check dart increases, the dart contacts the soft seat and then the hard seat to form a seal and close the check valve.

•

These valves each have an elastomeric soft seat and stainless steel hard seat. The initial seal is between the valve’s stainless steel check dart and the soft seat. These check valves can withstand 10,000 psi differential pressure and can be converted from velocity check valves to positive check valves by the addition of a spring. The flow area for the 1m “ OD B-1 valve is equivalent to a 5/16” port.

Camco BKCI-2 Chemical Injection Valve

Features and Benefits •

Valve constructed from stainless steel or nickel alloys

•

Nitrogen charged dome operation

•

Various packing materials available

Typical Applications •

The BKCI-2 valve offers metal seal nitrogen containment technology. Instead of the conventional bellows type design, the BKCI-2 uses a two-way metal seal piston for operation. Silicone fluid is maintained above the piston and acts as a barrier between the gas dome charge and sealing lips of the piston, which enables the valve to maintain nitrogen dome pressures to 10, 000psi.

•

Friction characteristics of the BKCI-2 are different from those observed on bellows operated valves. Once opening pressure is achieved, the piston will travel to the fully open position and allow maximum flow. Friction between the piston and housing acts as a buffer to help prevent valve chatter.
