Linc Level Controls
LINC Level Controls can activate alarms, provide a switch input for control systems, or perform a variety of desired switch operations actuated by a liquid or liquid interface
For more than 50 years, LINC Level Controls have outperformed in the toughest customer applications around the world. All LINC pumps are manufactured from 316 stainless steel to provide excellent corrosive resistance to chemicals in the harshest environments, such as outdoor installations and offshore platforms. When space is a concern, the small footprint of our pumps can provide pressures up to 15,000 psi to give you accurate chemical dosing when and where you need it most.
LINC level and flow switches monitor a variety of liquids and provide a pneumatic or electric signal to activate alarms, operate valves, or start and stop pumps. All our LINC level and flow switches are made to order from 316 stainless steel with a variety of sizes and configurations to meet your exact requirements. Even in the most challenging environmental conditions, you can count on the reliability of LINC for years to come.
Relays
The Williams Pneumatic Relays ensure proper air or gas flow rates for a given application
The Pneumatic Relay is a pilot operated valve designed to provide the higher air or gas flow rates necessary for pneumatic drive cylinders greater than 3 inches. The pneumatic relay is actuated by the pulses produced by the Oscillamatic Controller. A single acting pneumatic relay is used with pumps that have a piston return spring.
Air/gas pressure from a controller forces a piston and one or more attached poppet valves to move. The controller removes pressure and the spring forces both the piston and poppet valve(s) in the reverse direction. The PO3-6S relay has one poppet valve that connects the supply air/gas to the pump and blocks the exhaust when the controller applies air/gas to the relay piston. When the controller removes pressure from piston, the poppet valve stops the supply air/gas and connects the pump to the exhaust.
Controllers
The MK-II Oscillamatic Controller is a pneumatic pulser/timer used to operate the Williams series of pneumatically operated pumps.
The MK-II Oscillamatic Controller is a pneumatic pulser/timer used to operate the Williams series of pneumatically operated pumps.
The controller, consisting of an upper and lower chamber separated by a sliding spool, uses a capillary tube with a needle valve to transfer the supply air/gas from the lower to the upper chamber. While the controllers differ in their seals, MK-X using U-cup seals and MK-II, MK-VII, MK XIIA are using diaphragm seals, their operation is essentially the same. When the sliding spool is in its highest position, a pilot plug closes a vent and moves the supply air/gas to the pump or relay. In the spool’s lowest position, the reverse is true; the pilot plug prevents supply air/gas from entering pump or relay and opens the vent to let it exhaust. The spool then returns to its highest position and repeats the cycle.
