Spring

configurations

A new pinion design involves modifications to the internal springs. The BVA300 has pre-compressed

springs which allows different configurations. In this way, springs can be adapted to

different air pressures, facilitating safe, simple and fast maintenance.

Certificates

ISO

PED

ATEX

Spirax Sarco is certified by ISO 9001:2002

BVA310 to BVA335 are classified as Category SEP (PED 97 / 23 / EC)

BVA340 to BVA365 are classified as Category 1, procedure module A.

BVA300 are classified for use in potentially explosive atmospheres as Group II

Category 2, suitable for zones 1, 2, 21 and 22 in accordance with Annex VIII -

Directive 94 / 9 / CE.

Bi- directional

travel stops

The BVA300 pneumatic actuators are provided with bi-directional pinion travel stops which allow a

travel adjustment between 85° and 95°. These travel stops avoid superfluous forces and torques

which otherwise reduce an actuator’s service life.

Body labels

Double acting and single acting BVA300 actuators include labels which identify them.

ATEX EX Proof certification for use in explosive atmospheres is printed on the label.

Single acting actuators detail the quantity of springs according to the actuator configuration.
