Gate Valves Option Guide

From MDC Vacuum Products LLC
 

 
MDC circular C-Loc® gate valves can be fitted with optional high precision, modular mechanical position indicators (MPI). This new MPI system consists of two single pole double throw micro switches fitted with integral hinged lever and roller actuators. Each micro switch is wired in a normally open position. Normally closed
Products & Services
Snap action switches are mechanical switches that produce a very rapid transfer of contacts from one position to another. They are useful in situations that require a fast opening or closing of a circuit, such as a mouse button or appliance setting. Search by Specification | Learn more about Snap Action Switches
Dual in-line package (DIP) switches are electronic packages that consist of a series of tiny switches. DIP switches are used to configure computers and peripherals such as circuit boards and modems. Search by Specification | Learn more about DIP Switches
Rotary limit switches use physically-actuated levers to rotate a shaft and operate the contacts in a switch, making them change state. Search by Specification | Learn more about Rotary Limit Switches
Reed relays are electrically-operated switching devices that consist of two thin, magnetic strips (reeds) encapsulated in a glass envelope. They are used to switch industrial components such as solenoids, contactors and starter motors. Search by Specification | Learn more about Reed Relays
Toggle switches are actuated by moving a lever back and forth to open or close an electrical circuit. Search by Specification | Learn more about Toggle Switches
