A v-port ball valve has a “v” shaped ball instead of a round-bore ball. This allows the orifice to be opened and closed in a more
controlled manner with a closer to linear flow characteristic. DIE ERSTE provides several v-port balls in Series 35 with different
angles of “v”. Note that the long-term throttling operation in a certain percent open is no recommended.

Automation Accessories
Pneumatic Actuators
VT Series – Rack & Pinion Type
The VT Series rack & pinion actuators are reliable quality products, which can be relied
on to perform faultlessly under any difficult circumstances.. For double-acting mode , the
actuator is available in 11 sizes. Under the provision of common power supply (80 psi),
the output torque ranges from 8.02 to 2877 Nm (71 to 25469 in-lbs). For single-active,
also known as spring return type, 10 sizes are available.

Electric Actuators
Js Series
The Jexme electric actuators are made in new sizes from 34.3 to 597.8 Nm (303.6 to
5290.8 in-lbs), which are generally applied for ball valves with maximum size 6”, and
butterfly valves with maximum size 12”, and are available in on-off or modulating
versions, with a choice of duty cycles. All models include standard manual override, visual
position indicator, torque limiter and adjustable-position switches.

VSII™ Namur Type Solenoid Valves

for Valve Actuator
VSII™ namur type solenoid valve is specifically engineered to pilot pneumatic process
valve actuators. Using enhanced materials, VSII™ has an operating temperature range
from -20°C up to 50°C (-4°F up to 140°F). The most notable improvement is the patened
rotary sealing plate. It features in the field conversion form 3/2 to 5/2 action without the
need for tools or additional parts, and incorporates exhaust feedback to increase actuator
spring life span.

For other automation options, please consult with your DIE ERSTE representative.
