Bonnet Types
Plain Bonnet: Suitable for temperatures ranging from -17°C to 230°C.
Extension Bonnet Type 1: Designed for extreme temperatures, handling ranges from -45°C to -17°C and 230°C to 566°C.
Extension Bonnet Type 2 (Cryogenic):
• Integral Cast Type: Ideal for temperatures from -100°C to -45°C.
• Welded Type: Suitable for cryogenic applications from -196°C to -100°C.
Bellows Type: Used for specialized applications where complete isolation of the fluid is required.
Actuator Types
• Single-Acting Diaphragm Actuator: Actuator that uses a single diaphragm to create motion.
• Spring-Type Piston Actuator: Uses a spring-loaded piston for actuation.
• Double-Acting Piston Actuator: Employs pistons in a double-acting configuration, providing actuation force in both directions.
Diaphragm Materials
Cloth-Embedded Nylon: A durable diaphragm material reinforced with cloth.
Spring Range
• 20 to 100 kPa (0.2 to 1.0 kgf/cm²)
• 40 to 200 kPa (0.4 to 2.0 kgf/cm²)

Valve Action
• FO (Fail Open): Air to close, using a direct action actuator.
• FC (Fail Close): Air to open, using a reverse action actuator.
Optional Accessories
• P/P or I/P Positioner: Pneumatic or electronic positioners for precise valve control.
• Air Filter Regulator: Filters and regulates the air supply.
• Top-Mounted or Side-Mounted Handwheel: Manual operation handwheel for additional control.
• Limit Switch: Provides a signal indicating the position of the valve.
• Solenoid Valve: Electrically controlled valve for switching air supply.
• Motion Transmitter: Transmits the position of the valve stem.
• Booster Relay: Enhances the pressure signal for quicker response.
• Lock-Up Valve: Locks the valve in position in case of supply air failure.
• Air Lock Relay: Maintains the position of the valve upon loss of air supply.
• Others: Various additional accessories to customize functionality.
Performance
Flow Characteristics:
• Equal Percentage: Provides a non-linear flow characteristic, typically used for applications requiring fine control.
• Linear: Provides a linear relationship between valve position and flow rate.
Leakage:
• Metal Seat: Conforms to ANSI B16.104 Class II, with leakage less than 0.5% of maximum valve capacity.
• Soft Seat: Conforms to ANSI B16.104 Class VI, with leakage less than 0.00001% of maximum valve capacity.
Inherent Rangeability:
• 50:1: Standard rangeability.
