Valve Specifications

  1. Operating Pressure Range: Suitable for a wide range of operating pressures, depending on the chosen flange type (JIS, DIN, or ANSI)
  2. Temperature Range: -10°C to 180°C, depending on the selected seat material (NBR, EPDM, VITON, or PTFE).
  3. Flow-Control Capabilities: Bidirectional flow control with a wide range of flow rates, suitable for various pipeline applications and fluid types.
  4. Control System Interfaces: Compatible with hydraulic control systems, providing remote operation capabilities for demanding industrial pipelines.

Installation, Operation, and Maintenance

Follow these instructions for the safe and efficient installation, operation, and maintenance of the hydraulic remote flange butterfly valve:

Installation

  1. Confirm that the valve size, flange type, materials, and pressure rating match the intended pipeline application.
  2. Make sure the pipeline is clean and free of debris.
  3. Align the valve’s flange mounting holes with the pipeline’s flange holes.
  4. Insert the appropriate gasket between the valve and the pipeline flanges.
  5. Tighten the flange bolts in a criss-cross pattern to ensure even pressure distribution.
  6. Connect the hydraulic control system to the actuator, and test for proper operation.

Operation

  1. Use the hydraulic control system to operate the valve remotely, or manually control the valve’s position using the handwheel.
  2. Regularly monitor the valve’s performance, checking for signs of leakage, wear, or damage.

Maintenance & Troubleshooting

  1. Periodically inspect the valve for signs of wear, corrosion, or damage.
  2. Replace worn or damaged components as necessary.
  3. If leakage is detected, check the tightness of the flange bolts, the condition of the seat, and the gasket. Replace or adjust as needed.
  4. Regularly lubricate the stem and moving parts.
