Installation & Maintenance Instructions for

Mark 40/46 Float/Lever Control Valves

Warning: Jordan Valve products must only be used, installed and repaired in accordance with these Installation &

Maintenance Instructions. Observe all applicable public and company codes and regulations. In the event of leak-

age or other malfunction, call a qualied service person; continued operation may cause system failure or a general

hazard. Before servicing any valve, disconnect, shut off, or bypass all pressurized uid. Before disassembling a valve,

be sure to release all spring tension.

Please read these instructions carefully!

Your Jordan Valve product will provide you with long,

trouble-free service if it is correctly installed and main-

tained. Spending a few minutes now reading these in-

structions can save hours of trouble and downtime later.

When making repairs, use only genuine Jordan Valve

parts, available for immediate shipment from the factory.

1/4” through 2” Sizes

To be used with the Mark 70 I&M

The Mark 40 Float Valve and the Mark 46 Lever Valve are

of the same construction with the exception of the ac-

tuator. The Mark 40 is supplied with a oat actuator; the

Mark 46 is supplied with a lever, with a series of drilled

holes, for attachment to a customer supplied actuator.

Installation

Follow the installation procedure and cautions outlined

in the Mark 70 I&M with the following additional com-

ments:

Make the installation of the valve so that the oat (or

lever) is properly positioned relative to the tank (or actua-

tor). Note that the actuator assembly can be positioned

in any direction on the valve body by loosening the yoke

screw (19) and rotating the actuator to the desired posi-

tion. If, however, the actuator is to be rotated more than

90 degrees, the spring pin (21) should be removed from

the stem clevis (22) and the lever (24) removed from

the slot in the stem clevis. This will allow the actuator to

rotate without rotating the clevis pin on the stem (10),

which changes the seat adjustment. After the actuator is

in the proper position, check that the yoke (18) is prop-

erly seated on the body (1) and tighten the yoke screw.

Engage the lever in the stem clevis slot and replace the

spring pin.

The oat (34) can be adjusted up or down by loosening

the nut (25) and adjusting the oat to the desired posi-

tion.

Start Up

Follow the start-up procedure outlined in the Mark 70

I&M.

Mark 70 I&M for valve seat disassembly and reassembly.
