PNEUMATIC CYLINDER ACTUATORS, SERIES B
The Neles double acting and spring return B-Series piston type actuators are designed for u in both modulating control and on-off rvice. The ries B1C and B1J are designed to ISO 5211/1 when Metso
linkages are utilized. The actuators offer an extremely long cycle life and are well suited to operate almost any type of rotary valve.
When "stay put" is the requirement, the double acting B1C ries is the choice. This ries is available in veral sizes with torque outputs from 40 Nm to 100 000 Nm (29.5lbf ft to 73 756 lbf ft) for maximum supply pressure of 10 bar (145 psi).
If a failure mode is required, the spring return B1J ries should be lected. This line offers a lf-contained spring cartridge to provide failure in either the open or clod position. On butterfly valves, gmented valves and Q-ball valves, the actuator provides failure in the clod position, while a B1JA ries is available when failure in the open position is required. The spring return actuators are
栖息的意思available with a mid-range spring for 4 bar (58 psi) supply range, a lighter spring for lower supply pressure 3 bar (44 psi) range and a stronger spring for 5.5 bar (80psi) range. The actuators offer torque outputs from 50 Nm to 12 000 Nm (37lbf ft to 8851lbf ft)for maximum supply pressure 8.5 bar (124psi).
Adjustable travel stops
As with any Neles pneumatic/hydraulic actuator ,adjustable travel stops are standard for both the open and clod positions. End of stroke turning angle range is 85° to 95°. Optional travel stops 0° to 90° are also available.
Wear resistant bearings
Metal backed acetal bearings provide support on the upper and lower portions of the lever arm to reduce friction and expand the life of both the lever arm and the housing.
Corrosion resistance
The epoxy painted actuators have housings of rugged cast iron, with light-weight aluminium cylinders ano-dized for added corrosion resistance. Travel stops are stainless steel.
Self-contained spring cartridge
The springs in the B1J actuator are contained in a cartridge for added reliability and easy maintenance.
Spring to open or clo capability
The standard spring return actuator on ball valve can provide spring-to-clo or spring-to-open operation simply by changing the mounting position 90°. On a high performance butterfly valve, the standard unit offers spring-to-clo operation. An optional B1JA model is available for spring-to-open requirements.
High-and-low temperature construction
The standard unit can be ud in temperature upto 70°C (158°F). High temperature construction is availa-ble for temperatures up to 120 °C (248 °F). The standard unit can be ud down to -20 °C (-4 °F). Low tempera-ture design is available down (37 lbf ft to 8851 lbf ft).

High cycle option
中日互译在线翻译For applications where very fast and high quency operation is required.
ATEX compatibility
Standard construction ATEX approved.
Oversized cylinder options
The oversized cylinders (B1C 60, 75, 602, 752) are ud whenever the supply pressure is limeted, thus the actuators can achieve the required torques with lower supply pressure level.
Override options
Available override devices include a manual center-piece handle; a manual handwheel override; and a manual hydraulic override for high torque applications.
Emergency shut-down
Emergency Shut-Down (ESD) valves utilizing B1J actu-ators are offered to assure operation in the event of a fire or plant malfunction. The ESD device enables valve operational testing without cycling, e bulletin 6B21.

Lock-out device
Mechanical lock-outs are available to lock the actuator in either the open or clod position, when curity considera-tions are necessary .
Acessories and control devices
A variety of accessories are available including Neles posi-tioners and limit switches, position indicators, solenoid valves, transducers, relays, boosters and volume tanks etc.The B1C-ries actuator is designed for quarter-turn action for control as well as for on-off rvices. The double-acting cylinder actuator is pneumatically operated. The linkage pro-vides an output characteristic that surpass the nominal torque at the starting point (β = 0°).
Applications: E.g. quarter-turn valves. Compressor anti-surge and recirculate control. Damper drivers equipped with rack, shaft and lever arm.
