Samson pneumatski aktuatori TIP 2780, TIP 3277, TIP 3271
Application
Direct-way simple-action pneumatic actuators for industries, heating, ventilation and air-conditioning systems. First of all it designed for SAMSON type 3213, 3222, 3221, 3531, 3226, 3260, 3323, 3535 valves and series 240, 250 and 280 valves.
Characteristics
• Diaphragm-type actuators with internal springs
• Fail-safe action “actuator stem extends” and “actuator stem retracts”
• Ease of changing the fail-safe action
• Low friction due to rolling diaphragm
• Direct installation for type 2780-2 and 3277 provides exact location of additional devices, for example, indicator of stroke values.
Versions
- Type 2780 • Pneumatic actuator. Direct installation of positioner, limit switches and analog limit sensor for type 2780-2
- Type 3277 • Pneumatic actuator for integrated installation of positioner, limit switches and analog limit sensor
- Type 3271 • Pneumatic actuator with diaphragm square from 60 cm2 for micro valve to double actuator 2 x 2800 cm2
Further versions
Additional manual doubler for type 3277 and 3271 actuators.
Type Fire-Lock version (firefighting) provides during fire the installation in the safe position for type 3277 and 3271 actuators with diaphragm square 240, 350 and 700 cm2.
