solenoid and allow for manual operation by turning the manual bleed handle to the left to open and to the right to close. The valve(s) shall provide

easy access for removing all parts from the top of the valve without disturbing normal valve installation.

b2. Micro-powered solenoid actuator only

Micro-powered solenoid actuator (LEMA 1600HE) shall be with the correct adapter to be mounted on any valve (please refer to the back page for

detail). The controller shall communicate to the micro-powered solenoid actuator via two-way digital control pulses.

c. LEIT Key – The controller shall use one LEIT Key (powered by a 9-volt battery) to provide access and to activate the controller’s LCD screen.

3.1.3 Controller Accessories Descriptions

a. Stainless steel enclosure

For added protection the controller shall have the option to add a (304) Stainless Steel vandal resistant enclosure with strip perforations on top, allowing

light to enter the controller, plus a lockable hinged door. (Lock included)

b. Sensor adapter – The controller or the micro-powered solenoid actuator shall have an option to connect to all types of switch type sensors via the SKIT

sensor adapter. The SKIT adapter shall be used as an interface between the controller and a compatible rain, moisture or freeze protection sensor.

c. MV/P adapter: The controller shall have an option to switch on/off an AC or DC circuit via the RKIT relay interface adapter.The RKIT adapter shall be used

as an interface between the controller and AC switch device.

d. Swivel ﬁttings – Micro-powered solenoid actuator with globe valve shall be used with swivel ﬁttings as a union and shall allow, in case of repair, that the

valve may be brought to the surface to be serviced without removing the irrigation box or cutting the pipe. The swivel ﬁtting shall be constructed of

injected molded polypropylene, UV resistant. The swivel ﬁtting shall feature high impact strength plastic and be highly chemical resistant. The male thread

of the swivel ﬁttings shall be attached to both sides of the valve. The female thread side of the swivel ﬁtting shall have a large swivel 1", 11/2" or 2"

(FNPT) with encapsulated Nitric rubber “O” ring in such a manner that allows quick and easy tightening to a PVC male adapter without tools and teﬂon

tape. The swivel ﬁtting operating pressure shall not exceed 150 PSI.
