The ROSS Poppet Valve . . . A ROSS Speciality from the Beginning Positive Sealing Inlet air pressure forces the inlet poppet downward, pushing the poppet seal firmly against the seat. The higher the inlet pressure, the greater the sealing force. Note that the seal is engaged perpendicular to the seat; there is no sliding action to damage and wear the seal, or to cause erratic friction. Self-Cleaning and Dirt Tolerant The flow velocity for a given volume of air is dependent upon the area through which it is flowing. The smaller the area, the greater the velocity. In poppet valves, the...

Why do Poppet Valves Pop? ROSS poppet valves pop open and closed almost instantly. Surface areas of the double piston and poppet are carefully calculated to produce strong shifting forces in both direction. This results in a design which ensures high speed, repeatability and high shifting forces. 2/2 Normally Closed 1 - Valve Not Actuated External Pilot External Pilot 3/2 Normally Closed 1 - Valve Not Actuated Inlet Pressure External Pilot Inlet Pressure External Pilot © 2012, ROSS CONTROLS®.

Dale Series CP & CX Single Station Compact Poppet Valves The Series CP and CX 2- or 3-way valves are available in normally-open, normally-closed with solenoid and remote pilot configurations. The 2-way valves range from 3/8” to 21/2” pipe size with an impressive Cv range of 3.5 to 100. This high-flow capability is a unique and valuable feature in such a compact valve manifold design. The 3-way valves range from 1/2” to 1” pipe size and have a Cv range of 3.2 to 12.3. Series CP, CX Valve 2/2 Valves Ports: 3/8 & 1/2 These valves can be ordered with inline or manifold base-mounted...

Series CP, CX Solenoid Pilot Controlled Valves 2/2 Valve Dimensions – inches (mm) Port Sizes: 2 & 21/2 3/2 Valve Dimensions – inches (mm) Port Sizes: 3/8 & 1/2 Applications Examples Valve The CP series 3-way valves can be ported from the bottom and attach directly to the rod and cap end a cylinder. The CP series 3-way can also be supplied as a cartridge valve that can be machined directly into the cylinder heads. Both methods increase speed, eliminate line loss, improve cylinder control, and greatly reduce operating cost. © 2012, ROSS CONTROLS®. All Rights Reserved.
