General information Gate valves In 1957, Hawle invented the resilient-seated gate valve with multiple O-ring sealing of the valve spindle and had it patented. Today, this type of gate valve is the standard equipment in the field of potable water supply. On the basis of this patent further innovations have been developed by and by, among them, for example, the exchange gate valve, the combi valve, the gate valve with PE fusion ends, the push-fit socket valve, etc. Hawle gate valves are characterized by smooth operation, a long service life, and a great diversity of variants. dirt wiper locking ring of POM O-ring carrier spindle of stainless steel back seal sealed screws chambered flat gasket bonnet edge protection wedge nut resilient seated wege wedge guide body double-function socket tension lock for doublefunction socket base holding lugs for Hawle-Stop Figure: BAIO spigot end socket valve E2, type 451 www.hawle.de 05-A 01/2012 - subject to change without notice
General information Gate valves Gate valves for sewage water Pressure drainage systems in sewage water plants require gate valves that are suitable for buried installation, on the one hand, and that are equipped with a shut-off element resistant to sewage water and durably functioning, on the other hand. The Hawle gate valves for sewage water are provided with a shut-off blade of hard-rolled stainless steel and an O-ring package for shutting off. The sealing system prevents solids from sticking to the spindle and permits the exchange of the valve bonnet without taking the pressure line out of order.

Gerneral information Gate valves Actuator set The actuator set is used to open and close buried Hawle gate valves and butterfly valves. The actuator set consists of a watertight PE chamber, of the valve to be operated, and the actuator. All these components are factory preinstalled. The actuator set replaces costly and maintenance prone manhole constructions. All works (e.g. dismantling of the actuator) can be performed from ground level, thus avoiding the dangers and complications associated with entering manholes. Control system The related control unit can be accommodated in a meter box or alternatively in a nearby building. The actuator and the control unit are to be linked and connected by the customer via two cables (energy supply actuator, signal transmission). meter box with control unit surface box electric power control line actuator set valve Data communication The communication between the external station (actuator set with control system) and process control can be realized either via Ethernet Modbus TCP, RS485-Modbus RTU, GPRS, If you need more information on the actuator set, please contact us! www.hawle.de 05-C 01/2012 - subject to change without notice

General information Butterfly valves The Hawle PRO butterfly valve is provided with a proportional action gasket system. The gasket is accommodated in the body of the butterfly valve. When open, the same pressure is admitted to the butterfly valve from all sides, thus reliably preventing unintended deformations of the gasket. As soon as the Hawle PRO butterfly valve is moved to closed position, the valve gasket is pressed against the valve disc. The contact pressure depends on the potable water pressure. The proportional action sealing system ensures reliable gasket, on the one hand, and a long service life due to low wear of the gasket, on the other hand. The Hawle PRO butterfly valve is provided with the proven restraint loose flange system that is also used for the Hawle exchange gate valve. This is especially favourable when old valves have to be exchanged. Due to the integral loose flange system a dismantling piece is not required for new constructions. Hawle PRO butterfly valve - versions with handwheel with electric actuator with pneumatic actuator with extension spindle for buried installation

General information Pipe drilling saddles Hawle pipe drilling saddles for DCI, steel and AC pipes are provided with the universal strap system. Due to this universal strap system the same type of pipe drilling saddle can be used for pipe diameters DN 65 to DN 500. Adaptation to the respective pipe is effected via the holding strap and the saddle seal supplied with this strap. This universal strap system involves considerable economies in terms of storage. For AC pipes, regulations specifies holding straps with a width of 75-90 mm (depending on the drilling diameter) to protect the pipe. Therefore, the width of Hawle straps for AC pipes is generally 90 mm for all nominal widths. If the pipe outside diameter is unknown, a special universal holding strap can be used, which is adapted on site. (Only for potable water and sewage water pipes.) For plastic pipes (PE/PVC), pipe drilling saddles featuring the HAKU system are to be used. This system consists of two metal saddle halves provided with Hawle epoxy powder coating and connected via four screws. The width of HAKU saddle halves clearly exceeds the requirements specified in DIN 3543-2. We calibrate the saddle halves to the outside diameter of the plastic pipe. When connecting the saddle halves, an inadmissible deformation of the pipe is prevented by metal stops of the screws. Sealing to the pipe is effected via inserted gaskets in the upper and lower shell. The saddle halves shall be installed by tightening the screws all the way to the stop at the torques specified in the respective operating instructions, depending on the pipe outside diameter. Some versions of the HAKU system my be installed and connected with positive locking by means of wedge lock instead of screws. In addition to the numerous pipe drilling saddles without shut-off device, there are mainly four different drilling saddle systems with permanent shut-off device. Pipe drilling saddle type Hawlinger : drilling from above, shutting off via shut-off blade of stainless steel - see figure on the following page Milling saddle: drilling via integral milling cutter Valve saddle: lateral drilling, shutting off via resilient seated wedge Drilling saddles with auxiliary shut-off device: auxiliary shutting off by means of a shut-off blade of stainless steel, lateral drilling or drilling from top possible
General information Pipe drilling saddles Pipe drilling saddles Hawlinger Pipe drilling saddles type Hawlinger consist of the connecting element for the respective main pipe (e.g. universal strap system for DCI, steel, and AC pipes, and/or HAKU system for PE, PVC pipes), the shut-off mechanism consisting of a shut-off blade of hard-rolled stainless steel, and the Hawlinger bonnet with the three main versions: One upper outlet ( A ) One upper outlet and one outlet 90 to pipe direction ( U ) One upper outlet and one outlet in pipe direction ( S ) The outlets are either designed as ZAK sockets or provided with female thread.

General information Pipe drilling saddles Hawlinger for later drilling DIN 1988 prohibits the previous installation of service lines with the main line already drilled in the construction phase and the line just temporarily shut off via a shut-off device (e.g. gate valve). Due to the Hawlinger for later drilling as well as accessories such as a conduit and a special surface box it is possible to meet the hygienic requirements of DIN 1988, on the one hand, and to avoid the later digging up of traffic areas, on the other hand. Thus, drilling and commissioning of the service line can be done immediately before water is needed. Milling saddle Hawle milling saddles for PE/PVC pipes are provided with an integral drilling tool (milling cutter/punch) and an operational shut-off device. Therefore, no additional drilling device is required. The Hawle milling saddle is characterized by a robust O-ring shut-off mechanism and the two-stage feed mechanism (high feed rate up to milling, low feed rate during milling). Pipe saddles with auxiliary shut-off device Pipe saddles with auxiliary shut-off device are used wherever a line has to be shut-off temporarily, e.g. after drilling, but where no permanent shut-off valve is required. Shutting off is effected by means of a shut-off blade of stainless steel. After pulling the shut-off blade the seat of the saddle blade is sealed by fixing a gasket cover plate.
