DASH POTS FOR PEECO FLOW SWITCHES
|Dash Pots for PEECO flow switches are used wherever a turbulent flow of liquid requires switch action damping to avoid false actuation due to cavitation. The PEECO Dash Pot allows a delay period of up to 30 seconds before breaking contact and closing circuitry. Dash Pots dampen the chatter created by extremely high or low gaseous flow.
http://fleurdelissalon.net/?p=752 When there is the need to reduce or eliminate harmful or excessive motion, dashpots offer highly accurate motion control, including vibration damping, spring damping, and control of free fall velocity. Using high quality pneumatics in conjunction with a low expansion, precision glass cylinder and graphite piston technology. Dashpots are instrument quality pneumatic devices uniquely designed and optimized for accurate, repeatable force control at lower cost than other methods providing comparable functions and performance.

A dashpot is a mechanical device, a damper which resists motion via viscous friction. The resulting force is proportional to the velocity, but acts in the opposite direction, slowing the motion and absorbing energy.
Available on our Series N Flow Switch – these units are furnished with a slip-on steel cover. This .062 thick housing is NEMA 4X weather proof, by utilizing a special “O” ring seal fitted into a mechanical groove in the body; a standard on all of the non-explosion proof models. The housing & cover are both made of heat treated aluminum T-356 and are epoxy coated (for extra protection). Each of the four basic styles shown are adaptable to many other fittings and configurations.
Available on our Series E Flow Switch – All explosion proof models are rugged, heavy duty units exceeding all UL Code requirements. Each of the four basic styles are adaptable to many other fittings and configurations. Utilizing 1/4″ thick Heat treated aluminum cover (shown at right) with 5 fully engaged threads, these units are designed to encapsulate any internal explosion. All explosion proof models meet Class 1, Group D requirements for use in hazardous locations; all NEMA classifications available. The housing & cover are both made of heat treated aluminum T-356 and are epoxy coated (for extra protection). Other classes and groups are available. Conduit outlet: 1/2″ NPT on all models; 3/4″ and metric sizing available.
Available on our Series H Flow Switch – Utilizing ¼” thick Heat Treated aluminum cover with 5 fully engaged threads, all units are designed to encapsulate any internal explosion. In lieu of a bellows assembly a solid rod extends through a flexure tube brazed or welded into a S.S. ball fixture. Unit has been successfully field tested up to 10,000 psi. Wall thickness of the flexure tube will vary with pressure requirements. This model is recommended for all pressures over 600 psi. Each of the four basic styles shown are adaptable to many other fittings and configurations.
