OPTIONS -- Consult Factory for Pricing

JUNCTION PACKAGE
Complete factory assembled packages combine visual indication, solenoids, switches and transmitter in a single convenient UL, CSA, ATEX, or SAA certified assembly which saves labor and reduces cost. The simple package is shipped ready for installation, complete with a custom designed mounting kit for your specific application. Many options are available such as painted aluminum, epoxy coated aluminum or stainless steel housings including a standard 3/4" NPT conduit entrance and choice of 1 or 2 additional 1/2" NPT conduit entrances. The optional conduit entrances are drilled and tapped in the base of the position indicator housing and solenoid valves are screwed into the entrances. 22 to 16 AWG wire leads from solenoids, switches and optional transmitter are terminated in prelabeled, easy-access terminal strips protected inside the housing. Note: UL, CSA, ATEX or SAA approval requires complete package assembly by Proximity. Consult the factory for recommended UL, CSA, ATEX or SAA approved solenoid valve options.

FACTORY SEALED LEADS

Eliminate the possibility of conduit contamination and the need for seal fittings with Proximity's factory sealed (potted) leads. This seal has been UL tested to 6000 psi (422 kg/cm²) and listed for Class I, Groups A, B, C, D; Div. 1 & 2 atmospheres. Groups may vary depending on the switch model. Standard leads are 18 AWG and 36 " (91.44 cm) long.

AS-INTERFACE

AS-Interface allowing networking of up to 31 devices over a 2-wire network. Option for Mark 1 Magnetic Drive and Mark 4 Thru-Shaft Valve Position Indicators. Available with 1 or 2 incoroprated solenoid valves.

MOUNTING KITS
Mounting kits with drive yoke (see drawing), or slotted lever arm, bracket, fasteners and other zinc plated or stainless steel hardware fit over 2000 popular valves and actuators. A high strength spring tempered Monel drive yoke/coupling is tailored to fit securely to a specific valve or actuator stem. There is no slippage or binding. No special alignment fixtures are required due to switch offset design and yoke to stem engagement that makes installation a "snap". Each kit is specially designed for a particular valve or actuator; making field mounting simple with standard tools. Please specify make and model of valve or actuator on order.

Mounting kits can be used interchangeably with all models since external mounting features are identical. Rotary valves utilize direct drive couplings and a slotted lever drive is used with linear valves. Lever drives convert linear motion to rotary. Stainless steel visual indicators are standard for direct drive, automated quarter-turn valve applications.
