At Hy-Lok, we specialize in manufacturing valves and fittings for flow control systems, including diaphragm valves, which bridge the gap between the actuator and the flow control mechanism. This enables diaphragms to be used in sanitary flow control systems, where fluid purity is absolutely critical.
Below, we’ll go over some of the benefits of this reliable component and why you can count on Hy-Lok to provide the best quality diaphragm valves in Canada!
Low Maintenance and Easy to Clean
Diaphragm valves are designed to separate system fluid from the valve’s moving parts, which keeps the stem and actuator clean and free of contamination. The only parts that come into contact with the fluids are the diaphragm membrane and the body interior.
This design makes diaphragm valves essential for systems in food processing, pharmaceuticals, water purification, vascular infusion, IV therapy, and other equipment where cross-contamination can be detrimental to products and the health and safety of others.
Some flow control valves require stem packing, which can increase leak risk, whereas diaphragm valves don’t require this configuration. With fewer parts making contact with system fluids, diaphragm valves are also easier to maintain, as there aren’t as many parts that will wear out.
Resistant to Corrosive and Abrasive Materials
Many process fluids can be highly acidic, abrasive, or corrosive, and with the wrong materials, harsh conditions can damage your flow control valve, leading to system failure.
Our diaphragm valves at Hy-Lok are designed with 316L VIM/VAR and A479 stainless steel, which offer excellent chemical and corrosion resistance against harsh process fluids.
Leak-Proof Sealant
Another key aspect of operating sanitary fluid systems is maintaining a secure seal to prevent the formation of leak paths. Diaphragm valves are designed with an anti-leak seal and a tight shut-off mechanism to keep all process fluids in the same, consistent direction.
Precise Flow Control
Diaphragms have a great benefit that other flow control components lack—they can adjust flow rates with a very high precision. This is a huge asset for tasks like food mixing, where exact ratios and consistency are absolutely critical to the product’s outcome.
This mechanism is completed by adjusting the diaphragm’s lift distance off the seat, so you can create the exact flow rate you require during system operation.
Available for Low-Pressure and High-Pressure Systems
One downside to many diaphragm valves on the market is that they are usually designed for low to moderate-pressure systems. At Hy-Lok, we offer our DV Series pneumatic actuator diaphragm valves in low, medium, and high-pressure ratings.
Our DV Series valve has a maximum working pressure of 3,000psig (207 bar), and an actuation pressure of 70-100psig (4.9-8.2 bar).
Whether you need a low-pressure or high-pressure compatible valve, you can find exactly what you need from Hy-Lok Canada!
Get Quality Flow Control from Hy-Lok Canada
Sanitary systems require a precise, reliable flow control and sealant that you can’t get from just any valve or fitting. Diaphragm valves offer a leak-proof sealant, excellent pathway control, and even allow you to adjust flow rates to your equipment’s needs.
