Product catalog summary

Standards and Specifications
The resilient seated gate valve complies with EN 1171, EN 1074-1, and EN 1074-2 standards, featuring a smooth, straight-through bore. It is designed for use with PE fusion tails in combination with PE pipes according to EN 12201 and DIN 8074, rated at PN16/SDR11.

Construction Features
The valve includes PE tails that are screwed and sealed into sockets, ensuring high-performance sealing with two separate seals and a support liner. It can be connected to PE pipelines via butt fusion or electrofusion. The Hawle E3 model features a double bayonet O-ring carrier connecting the spindle to the bonnet, which is epoxy powder coated for corrosion protection. The spindle is made of Duplex stainless steel, and the wedge guide is crafted from wear-resistant POM material. The wedge is flexible, linked with vulcanized elastomer to the wedge nut, which has a long thread length for higher torque tolerance. O-rings and lip-seals in the bonnet are replaceable under operating pressure. The valve is suitable for buried installations and can be operated by automatic actuators.

Materials
The body, bonnet, and centering flange are made of ductile iron (EN-GJS-400-15) with an epoxy powder coating. The wedge is also made of ductile iron, with the DN 50 variant made of brass with vulcanized elastomer. The spindle is made of Duplex stainless steel with a polished area for O-ring sealing. O-rings and gaskets are made from EPDM elastomer.

Dimensions and Weights
The document provides detailed dimensions and weights for various DN sizes, ranging from DN50/D63 to DN200/D225, with specifications for weight, height, length, and other critical dimensions. All technical data, dimensions, and weights are non-binding and subject to changes.
