Lug Style Butterfly Valve | 578

Lug Style Butterfly Valve - Overview

The Lug style butterfly valve has all-plastic housing which combines quality and durability. Through the use of fibreglass-reinforced polypropylene, the valve's weight is greatly reduced. This simplifies not only the installation of the valve but also saves on the storage cost. The valve can be used reliably in highly corrosive applications and is excellent for use with aggressive media. The system allows the exchange of individual system components at any time - quickly and easily, without much effort. Since the actuation torque is strongly dependent on the internal pressure, type 578 is optimally designed in this area. The maximum nominal pressure is 10 bar on both sides at 20 °C. A further benefit of this is the long life span since the valve is less exposed to wear and tear.

Lug Style Butterfly Valve - Features
- Corrosion resistant
- Stable and Reliable
- Easy maintenance
- Long life span
- Minimal operation torque
- Can be fitted with an actuator (optional)
- Lever positioning clearly marked

Wafer Check Valve | 369

Wafer Check Valve - Overview

The type 369 Wafer Check Valve is designed especially for large installations. It requires little maintenance and is extremely compact. The design is optimised for installations between ISO/DIN as well as ANSI/BS connections. The flap traps can be installed either horizontally or vertically. When the medium flows, it opens up the plate of the flap trap, allowing the medium to flow through. The flap closes again if the medium pressure falls below a certain threshold. The flap traps of Type 369 are intended to prevent media from flowing back within the allowable pressure and temperature range. The flap traps are available with or without a return spring made of V4A or Hastelloy. This is suitable for use in water treatment and the chemical process industry.

Wafer Check Valve - Features
- Self-closing check valve
- Horizontal or vertical installation (water column/gravity / optional spring)

Water Applications Butterfly Valve | 565

Water Applications Butterfly Valve - Overview

The new Butterfly Valve 565 is the best choice for optimising piping systems built for water and a wide range of other applications. It comes at a significantly lower initial cost, due to its lower weight in terms of storage and transportation. Installation is quick and easy. It is extremely durable, ensuring minimal maintenance and a long life span. The valve comes in the same installation length as metal solutions so exchanging your metal valves for plastic ones will not require any additional work on the pipes or new designs. Thanks to its low weight, a single person can lift and install a valve in just a few minutes. It's low weight therefore significantly reduces the need for costly transportation and personnel. High-performance thermoplastics protect it from abrasion and corrosion, even under harsh conditions such as water hammers. The results are a reduction of both maintenance costs and production stops. In cooling applications, the plastic solution has a clear advantage in that its condensation is much lower. With its standard interface, the valve can be upgraded with various modules, such as the smart actuator. This allows for automation and digitisation of your systems, making them even more cost-effective and efficient.
