SSA/P Series 24 Vac Electronic

Valve Actuator: Floating or

0 to 10 Vdc Control

Fail-in-Place

Siemens Industry, Inc.

Description

The 599 Series SSA/P Electronic Valve Actuator requires a 24 Vac power supply and

receives a 0 to 10 Vdc or a floating control signal to control a valve. This actuator is

designed to work with 599 Series Zone Valves with a 1/10-inch (2.5 mm) stroke and a

threaded valve bonnet that fits the actuator.

Features

• Direct-coupled installation without tools

• Manual override with hex wrench

• Visual position indication

Application

For use in heating and cooling HVAC applications with Siemens 599 Series Zone

Valves that need 24 lb (105N) nominal force.

SSA/P Series Electronic Valve Actuator 24 Vac Floating or 0 to 10 Vdc Control Manual Override Technical Instructions Document Number 155-710 January 12, 2018 The actuators can be driven manually to any position between 0 and 1 with a 3 mm hex key. The actuator will maintain its position until power is provided or restored. A control signal from the controller, however, will take priority over any manual position.

See Figure 8 for referred positions “0” and “1” on the position indicator disc. SSA61U and SSA81U Normally Closed • When the position indicator disc is at the "0" position the output shaft is extended (two-way valve closed).

SSA/P Series Electronic Valve Actuator 24 Vac Floating or 0 to 10 Vdc Control Troubleshooting Technical Instructions Document Number 155-710 January 12, 2018 See Wiring for proper connections. If the actuator does not provide full flow or full close off, check that the actuator is properly attached to the valve. If not, turn power off, tighten the bonnet ring on to the valve completely, and power up to recalibrate. If the actuator becomes inoperative, replace it.
