tech level ball valves High pressure
CONSTRUCTION
All GMC
ball valves (both BVT and BV series) are designed to accommodate the AMBV
adapter, which enables connection to a rotary actuator. The AMBV
assembly consists of three components:
- a flange interface that couples with the actuator housing,
- an internal spindle that links the valve spindle to the actuator’s drive mechanism,
- a threaded retaining ring that secures all parts together.
All three
components are manufactured from galvanized steel, and the adapter is designed
in accordance with ISO 5211. All valves can be supplied with Belimo®
actuators, available in 24 V modulating or on/off versions, or 230 V on/off
versions.
INSTALLATION
When
actuators other than those recommended by GMC are used, it is essential to
respect the required opening/closing torque and the maximum permissible weight
for the BV + AMBV assembly. If the maximum supported weight is exceeded,
suitable external supports or restraints must be provided.
APPLICATION
Motorized
ball valves of the BV–BVT series in the GREEN line are classified as “Pressure
accessories” under PED Directive 2014/68/EU, Article 2, paragraph 5. The
entire product range is suitable for use with refrigerant R744 (CO₂),
classified in Article 13, paragraph 1(b) of the PED Directive as a Group 2
fluid — non‑toxic, non‑flammable, and non‑explosive — and listed as A1
class in Annex E of EN 378‑1.
According
to Directive 2014/68/EU, the hazard classification of the product depends on:
- the type of fluid used,
- intrinsic dimensions (DN),
- maximum design working pressure (PS).
Refer to
the technical tables in the BV–BVT sections for the hazard category of each
specific model.
The AMBV
adapter and Belimo® actuator are excluded from the scope of
PED Directive 2014/68/EU.
