Description

The BFK range of Wafer style ductile iron Butterfly valves are available with pneumatic, electric or manual actuation. The BFK series has a cast iron body, 304 S.S disc and an EPDM seat making them suited to a wide range of general water applications.

These wafer butterfly valves will fit all standard flanges and are operated by either a lever or gear box (ISO 5211 mounting pad allows direct mounting).

Designed & manufactured in accordance with API609, inspected and tested in accordance with API598. Common applications include water trucks, irrigation and non corrosive industrial applications.

If sizes above 300mm are required please see BFD series (cast iron, 316 SS disc).

MANUAL ACTUATION:

PNEUMATIC ACTUATION:

ELECTRIC ACTUATION:

The OM series is a robust range of 1/4 turn electric actuators suitable for the on/off activation of Ball or Butterfly valves.

A powerful motor with inbuilt thermal protection drives a pre-lubricated heavy duty steel gear train running in bronze bushes. They are encased in a powder coated die cast protective housing that has an IP67 rating (dust tight and submersible for limited periods).

All models have a visual position indicator and a manual override.

The ISO 5211 mounting and female square drive allows direct coupling to valves with a similar configuration.

Standard models drive through 900 and can be fitted with voltage free contacts for end of stroke feedback.

Positioner models with 4-20mA or 2-10v modulating control are also available in all sizes.

STANDARD FEATURES:

  • IP67 weatherproof rating and Humidity up to 95%.
  • Ambient temp. -5°c ... +600G.
  • Duty cycle is 30% to 75% depending on ambient temperature, voltage and actuator model, and relates to the 135°G thermal motor protection. (some modulating versions have a 75% duty cycle)
  • Always allow a 35% safety margin when sizing torque requirements.

OPTIONAL FEATURES:

  • Torque limit switch (overload protection).
  • Anti-condensation heater - 15 watt.
  • Two SPOT voltage free micro switches and cams (end of stroke feedback).
  • Potentiometer and position transmitter (4-20mA feedback).
  • Modulating control (4-20mA or 2-1Ov input and feedback).
