The GF Piping Systems range of plastic diaphragm valves includes manual, pneumatic and electric units in various sizes and for different pressure ranges, guaranteeing the right valve for any piping system. Designed to optimize the flow profile of the liquid inside the pipe, these valves are made entirely of plastic for excellent durability and reliability. The modular design allows them to be easily adapted to process conditions.

Unlimited versatility

These diaphragm valves are modular, which allows them to be configured to accommodate any connecting standard and technology, chemical resistance or actuation.

Optimized flow profile

GF Piping Systems has streamlined the body design of all of its diaphragm valves to improve the internal flow profile and boost overall system performance.

For plastic-optimized design

The innovative plastic thread connection guarantees reduced maintenance effort compared to conventional diaphragm valves.

Ideal for any piping set-up

Whether manual, pneumatic, (electric), small or large, GF Piping Systems diaphragm valves are guaranteed to improve the operational efficiency of any installation.

Diaphragm Valve 317

Large-scale pipes require a diaphragm valve with equally large dimensions, which is why the GF Piping Systems range includes the Type 317. Fitted with a graduated optical position indicator, the proven screw design provides excellent flow control.

Diaphragm Valve 514

Intended for use in numerous applications from chemical processing to water treatment, GF Piping Systems Type 514 diaphragm valves offer very linear flow characteristics with the highest flow rate available on the market. The true union connection of the Type 514 allows for fast installation and exchange.

Diaphragm Valve 515

Intended for use in numerous applications from chemical processing to water treatment, GF Piping Systems Type 515 diaphragm valves offer very linear flow characteristics with the highest flow rate available on the market. The spigot of the Type 515 allows for durable installation with no dead space.

Diaphragm Valve 517

Intended for use in numerous applications from chemical processing to water treatment, GF Piping Systems Type 517 diaphragm valves offer very linear flow characteristics with the highest flow rate available on the market. The flange connection of the Type 517 allows for mechanical jointing to nearly everything.

Diaphragm Valve 519

Ideally suited to flow control and open/close duties, the Type 519 diaphragm valve is a three-way zero-static variant that can be used in a wide range of applications. Dead space is virtually eliminated around the valve thanks to the innovative design.

Diaphragm Valve 604/605

The compact and pneumatic Type 604/605 diaphragm valve is designed for high cycle frequency. They are extremely resistant to corrosion, leakproof and maintenance-free, and can also be installed in confined spaces.

Diaphragm Valve DIASTAR Six

Engineered specifically for low-pressure applications, DIASTAR Six diaphragm valves are a cost-effective solution wherever top reliability, zero corrosion and optimized flow are required. The compact dimensions make them easy to install and remove.

Diaphragm Valve DIASTAR Ten

The ideal fail-safe diaphragm valve for standard applications, the DIASTAR Ten is highly resistant to chemical corrosion and suitable for use with abrasive media. Rotatable air connections make installation simple, while multiple accessories are available for enhanced performance.

Diaphragm Valve DIASTAR Ten Plus

For applications in which pressure is applied from both sides of the diaphragm valve, opt for the DIASTAR TenPlus. Like the DIASTAR Ten, this valve is easy to install, will not corrode and controls the system flow rate exceptionally well.

Diaphragm Valve DIASTAR Sixteen

Designed by GF Piping Systems for installation in high-pressure water applications, the DIASTAR Sixteen Diaphragm Valve maintains a stable temperature, has an excellent pressure rating and is extremely efficient. It is also the perfect solution for all high-purity and cleanroom applications.

e-Diastar

The electric diaphragm valve e-Diastar allows simple automation without compressed air. Benefit from short downtimes thanks to fast and easy installation or retrofitting of manual diaphragm valves and lower maintenance costs.
