2 Basic safety notes

2.1 Intended use

The pressure maintenance valve has been designed for

installation in a machine in order to temporarily prevent the

pneumatic consumer from venting through the valve if there is a

loss of air pressure in the supply line. Therefore a temporary

force or position maintenance can be implemented via different

actuators. This is especially useful for grippers where a

mechanical grip force maintence solution is not possible.

lThe product is intended for installation in a machine/

automated system. The applicable guidelines for the machine/

automated system must be observed and complied with.

lThe product is intended for industrial use.

lThe product may only be used and operated within the scope

of the technical data and the specifications in this

manual }3 [/9].

lAppropriate use of the product includes compliance with all

instructions in this manual.

2.2 Constructional changes

Implementation of structural changes

By conversions, changes, and reworking, e.g. additional threads,

holes, or safety devices can impair the functioning or safety of

the product or damage it.

lStructural changes should only be made with the written

approval of SCHUNK.

2.3 Ambient conditions and operating conditions

Required ambient conditions and operating conditions

Incorrect ambient and operating conditions can make the

product unsafe, leading to the risk of serious injuries,

considerable material damage and/or a significant reduction to

the product's life span.

lMake sure that the product is used only in the context of its

defined application parameters, }3 [/9].

lMake sure that the product is a sufficient size for the

application.

lMake sure that the environment is free from splash water and

vapors as well as from abrasion or processing dust. Exceptions

are products that are designed especially for contaminated

environments.

read and understood the complete assembly and operating

manual.

lObserve the national safety regulations and rules and general

safety instructions.

The following personal qualifications are necessary for the

lAvoid any manner of working that may interfere with the

function and operational safety of the product.

lUse the product as intended.

lObserve the safety notes and assembly instructions.

lDo not expose the product to any corrosive media. This does

not apply to products that are designed for special

environments.

lEliminate any malfunction immediately.

lObserve the care and maintenance instructions.

Basic safety notes

8 07.00 | SDV-P / SDV-P-E / SDV-P-E-P | Assembly and Operating Manual | en | 389561

lObserve the current safety, accident prevention and

environmental protection regulations regarding the product's

application field.

2.6 Notes on particular risks

The general rule is:

lThe pressure maintenance valve temporarily prevents the

venting of the pneumatic module if there is a loss of air

pressure in the supply line. For this reason it is always

assumed that residual energy is stored in the system.

lTherefore the product must be ventilated before carrying out

any assembly, conversion, maintenance or adjustment work.

Here, it must be checked which module and which function is

triggered by this -> It is necessary to ensure that no person

can be harmed.

lFor all work, secure the product against accidental operation.

lAny hazards that arise for downstream consumers must be

identified separately and protected against by the operator

lOnly qualified personnel may disassemble the product.

lPerform maintenance, modifications, and additions outside

the danger zone.

4 Description

The SDV-P consists of two check valves connected in parallel,

which open when pressure is applied and reciprocal vent the

return direction.

At a pressure failure of the supply line, the check valves close

and prevent a pressure drop.
