Fishe G Series Pneumatic Actuator

The Fisher G-Series Pneumatic Actuator is a heavy-duty pneumatic actuator converting compressed air into mechanical torque to operate rotary valves. The actuator is widely used in high-risk environments such as Safety Instrumented Systems (SIS), High Integrity Pressure Protection Systems (HIPPS), and Emergency Shutdown (ESD).

High Torque Output

Provides double-acting torque up to 6,000,000 lb-in (≈678,000 Nm) and spring-return torque exceeding 3,000,000 lb-in, suitable for large valves and high-load applications.

 

Fast Response

Designed to move large volumes of air quickly, making it instrumental in rapid valve actuation and emergency shutdown systems.

 

High Durability

Protective coatings and premium components allow reliable operation in constant vibration, wide temperature fluctuations, and corrosive environments.

• Large inventory to support fast delivery and urgent replacement needs
• Short and stable lead times even for non-stock models
• Multiple logistics options for global shipments
• Professional technical support from experienced engineers
• Competitive pricing with a one-year warranty
• Trusted by industrial clients worldwide

Q1: What types of valves can the Fisher G-Series actuator drive?

A: It is typically used with quarter-turn rotary valves, including ball valves, butterfly valves, eccentric plug valves, and triple-offset valves.

Q2: What fail-safe options are available?

A: The actuator supports spring-return configurations for automatic fail-open or fail-close action, as well as double-acting models for controlled bidirectional operation.

Q3: What is the typical lead time?

A: For standard stock items, orders can usually be shipped within one week, depending on the destination. For special or customized products, lead times are confirmed in advance to meet project schedules.

Q4: How do you ensure product quality and after-sales support?

A: Each unit undergoes strict quality inspection before shipment to ensure reliable performance. We also provide a 1-year warranty, along with long-term technical support and spare parts availability.
