2-Way Diaphragm Valve | Type 514-519

2-way Diaphragm Valve - Overview

Diaphragm valves are used for regulating, controlling, closing, and monitoring volume flows. This is especially useful when transporting contaminated, aggressive or abrasive media. This type of valve has distinctive advantages due to its simple function and optimised design. Only the valve body and diaphragm come into contact with the medium. The valve is suitable for use with gases and liquids and can be used in any location and drained completely. Unlike other Valve Types, no pressure surges can be caused by closing the diaphragm valve. This Valve Type comes as a manually operated valve or an automatic valve.

2-way Diaphragm Valve - Features
- Complete plastic valve - no metal screws
- No corrosion in aggressive media/environment
- Constant leak-tightness
- No need to re-tighten
- Highly stable connection of upper part and valve body using buttress thread
- Maximum flow and linear characteristic curves for easier control
- Free of dead space, sealing web lies close to the pipe wall
- Durable
- Lockable
- Position Indicator
- Can be fitted with an actuator or electrical feedback unit

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
- Can be used with electric position indicators (optional)
- Use as lugged valve with threaded bushes integrated into the housing
- Lower weight than metallic butterfly valves
- Low wear and tear: up to 50 % lower operating torque than centric valves
- Leak-tightness within and without: double, internal axis gasket on both sides
- Lockable hand lever

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)
- Installation between both ISO/DIN and ANSI/BS connecting elements
- Simple installation
- Highly resistant materials
- Robust design
- Virtually maintenance free
- Parts that come into contact with media are highly resistant plastics and elastomers
- Optimised flange gasket made of EPDM/FKM installed in the valve housing. Suited for fluted connecting elements
- Disc seals available in EPDM/FKM and are installed in plates
- For pulsating flow, flap traps with reset spring (stainless steel V4A/Hastelloy C) available. Reduces noise development
