2Design

Semi-rotary drives of the DAPS series are compact in design and have simple and

robust mechanics with little wear and tear. The design of the product is dependent

on the product design and may differ from the representation shown in Fig. 1

( Fig. 1).

Through the housing, a shaft is guided outward on both sides. Through this, the

reaction torque is transmitted to a process valve ( Fig. 1, 9 ) and, if applicable,

a limit switch or sensor box ( Fig. 1, 1 ).

The flange to the process valve is designed in accordance with IS O 5211. Four

mounting threads on the top are used for mechanical attachment of a limit switch

or sensor box ( Fig. 1, 3 ). The housing side has a hole pattern for valve attach-

ment in accordance with VDI/VDE 3845 (NAMUR).

Depending on the version, the DAPS is designed as a single-actin g or double-acting

semi-rotary drive.

The housing of some semi-rotary drives has, on t he process valve port side, a leak-

agegroove( Fig. 1, aJ ) through which the leakage of an untight process valve

can escape.

The single-acting design with spring return is e quipped with different spring forces

for use with different supply pressures.

The DAPS...-MW product version described here is equipped with a handwheel -

for manual emergency override in a pressureless state.

The product is available in various designs. These operating instructions describe

the following product variants:

3 Function

The piston movement of the DAPS is converted to a rotary movement by means of

yoke kinematics (Scotch yoke). These kinematics are only effective within an angle

of approx. 90°.

For double-acting semi-rotary drives:

Pressurising and venting of the cylinder chambers

cause the piston in the DAPS to move back and for th.

The linear motion of the piston is transformed into a

swivel motion of the transmission sh aft.

Fig. 3

For single-actin g semi-rotary drives:

Return is through spring force.

Product designs with different spring strengths are

available (  Fig. 2 ).

Fig. 4

The screwed-on processing valve records the moment of reaction of the semi-

rotary drive. The torques permitted in accordance with the tec hnical specifications

( c atalogue www.festo.com/catalogue) apply here.

The handwheel can be used to change the position of the drive when the supply

pressure is switched off (manual emergency override).

Neutral position

If the indicator is located centrally, the

handwheel is in a neutral position.

– The piston can be moved freely.

– The drive can be operated pneumatic ally.

Indicator in left-hand position (inside)

A) Double-acting drive:

Turning the handwheel anti-clockwise

moves the indicator inwards.

– The process valve opens.

B) Single-acting drive:

Turning the handwheel clockwise moves the

indicator inwards.

– The process valve closes.
