Features:
- Manufactured to AS/NZS 2638.1, Dobbie metal seated gate valves feature high quality ductile iron body and cover castings, providing superior strength and substantial resistance to impact damage.
- Precision machined stainless steel has been utilised for the manufacture of valve spindles, providing a significant level of corrosion resistance and high strength.
- Valve gates DN80 – 300 are manufactured from dezincification resistant copper alloy. Larger sizes feature polymeric coated ductile iron gates with copper alloy sealing rings.
- High mechanical strength and wear resistant engineering plastic thrust washers ensure low torque requirement for both sealing and cracking operations.
- A robust gland with copper alloy sealing bush, incorporates two O-ring seals and a wiper ring, ensuring both reliability and longevity of service. O-rings may be serviced or replaced with the valve fully open under maximum operating pressure.
- Integral feet provide a stable platform and lifting points have been included in the design to aid safe installation.
- Valves may be operated using a key, handwheel or via gearbox reduction (IP68 rating on supplied gearboxes is standard).
- Fusion bonded polymeric coating to AS/NZS 4158 provides excellent protection from corrosion and abrasion.
- May be installed in either horizontal or vertical position.
- Available in PN16 or PN 35 pressure classifications in either clockwise closing (CC) or anti-clockwise closing (ACC) configurations.
