The LS-1B Elevator Limit Switch is designed primarily for use in elevator hoistways as Access, Slow Down, Normal, and Final Limits. The light weight durable construction of the LS-1B switch results in a reduced noise level and is designed for extended reliability.
Mounted directly onto the main jack connection, the Pipe Rupture Valve (PRV) is simple to adjust and extremely reliable in operation. Should an overspeed of the elevator occur, the damped closing of the PRV ensures a quick but smooth slowdown of the car. Slowing to a stop is standard; slowing to a down creep speed is optional.
Grooved or NPT straight through line connections enable the customer to attach the PRV to the existing cylinder and pressure line connections in the shortest possible installation time.

The Permanent Magnet Switch (MV) is designed primarily for applications requiring trouble free service. This switch provides a cost effective and simple solution for environments where mechanical contact between the actuating vane and switch is not desired.
Switches are available in two configurations, SPDT with one normally open & one normally closed contacts and DPDT with two normally open & two normally closed contacts.
The Permanent Magnet Inductor Switch (LDS-3004A) is intended for use on hydraulic and electric elevators with speeds up to 400 feet per minute and one floor run control. The LDS-3004A is made to interface with either relay logic, micro-processor or programmable logic controllers. The horseshoe shaped inductor switch provides noiseless sensing of slowdown and landing positions of the elevator.
The LDS-3004A Inductor Switch features solid metal construction and uses both a normally open and a normally closed contact reed switch as standard.
The Isolation Couplings (ISO) are available in three sizes both grooved and threaded. These couplings are designed for electrical isolation with a Dielectric Strength of 42 kV and will also help in the reduction of vibration and noise from being transmitted to the cab. The maximum operating temperature for these Isolation Couplings is 225º F (107º C).
All Isolation Couplings are designed to meet or exceed ASME A17.1/CSA B44.
The Shut Off Valve (SOV) is used to isolate one section of the system from another. All Shut Off Valves are constructed of ductile iron bodies and use a stainless steel ball. A locking device is standard on all sizes.
(includes Ball Valve & Handles}
The Muffler (MU) provides superior noise suppression for most standard
power unit installations. The unit working pressure is 1200 psi and it is 11-3/4” long.
Unit diameter for 2” size is 6-5/8” and 8-5/8” for other sizes.
The EECO Hydraulic Dampener (EHDN) is extremely effective in suppressing the sound and pulsation present in hydraulic elevator systems. The EHDN has a minimum burst pressure of 6000 psi with an ASME A17.1/CSA B44 allowable working pressure of 1200 psi. Unit diameter is 8-5/8” and the length for 2", 2.5", and 3" is 11.75". The 4" outlet unit has a diameter of 10.75" and a length of 13.75".
This is only a test.
Mounting brackets and Clamp are available for mounting the LS-1B & MV-4C model switches to the rail. Brackets are designed to work with 8, 12, & 15 pound rails. Part# 9733A. Contains one mounting bracket, two clips, and two bolts. Available as individual kits or in a case of 25.

The Thermal Switch is used to prevent the liquid temperature in the Hydraulic Power Units from rising above its maximum operating temperature. These switches are factory pre-set at a temperature setting of 1450 F (630 C). The one piece brass casing houses a bi-metallic, normal closed SPST snap switch. They are NEMA 4 and IP65, UL listed and CSA approved, which is rated for 15 amps @ 125 VAC, 10 amps @ 250 VAC. Mounting is accomplished by a 1/2" NPT and electrical termination by two 18 AWG, 36 inch long wires. (Per ASME A17.1/CSA-B44 3.26.6.5)
The Thermal Switch Assembly is required to be installed on all Hydraulic Power Units, per ASME A17.1/CSA‐B44 3.26.6.5, to prevent the oil temperature from rising above its maximum operating temperature. This assembly can be used in both Submersible and Dry Power Units.
The switch is factory pre‐set at a temperature setting of 145º F (63º C) and will fit in a tank up to 44" tall. Conduit length is 19" and can be trimmed if necessary for a shorter tank. For more information on the electrical characteristic of the switch see Sales Bulletin SB‐026.
A Dynamic Viton seal replacement kit (P/N 5131D) for your in-service UV-5A series valves (including UV-5A "S" series, UV-5AT and UV-5ATC valves). This kit contains the O-Rings for the moving parts of 3 Valves.
Since January 2001, all EECO valves have been manufactured with Viton seals. If you are replacing any of the major components listed on this page (which are supplied with Viton seals) in an EECO valve manufactuered prior to January 2001, EECO recommends that you also replace the older valve seals in the remainder of the valve with the newer Viton seals.
The 1/8” NPT Jack Bleeder Assembly is compact and easily installed. This bleeder is rated at 1500 psi. The barbed bleeder screw enables use of a 1/4” I.D. soft plastic or rubber tubing to direct oil into a container while bleeding the jack.
A thermostat that is field adjustable by a fine adjustment trim screw which can activate a viscosity
control system. The thrermostat is UL and CSA recognized for a maximum of 1500 watts at 230 volts AC
with a single contact. The unit has a heat sensitive base plate which can be mounted directly to the
outside of a hydraulic tank or by an aluminum “L” bracket with little loss of sensitivity.
This switch can be used to control pump/motor running in bypass mode to heat up the oil in lieu of
a tank heater or as a control to turn on/off an oil cooler and/or a tank heater. The switch is normally
closed and is open above the set temperature.
Specifications:
Range: Adjustable from 75ºF (off) to 525ºF
Rotation: 310 Angular Degrees
Terminal Connector: #6-32 Screw
The EECO Transfer valve allows the transfer of hydraulic oil between chambers in multi-stage jacks equalizing the hydraulic pressure during the resynchronization procedure.
