DSV® Sanitary Check Valves in the Pharmaceutical Industry: Explore Our eBook

In sanitary manufacturing applications that employ the use of fluid systems, such as in the pharmaceutical industry, regulating fluid flow and pressure is essential to maintaining high product and production quality. Common issues—such as backflow, water hammer, and cleanliness – significantly affect the overall effectiveness and efficiency of the system. For these situations, DSV® sanitary check valves serve as an ideal solution.

Why Are DSV® Sanitary Check Valves Important?

Unlike other check valves available on the market, DSV® sanitary valves meet 3A sanitary standard and are designed for use in applications with high sanitation requirements. As such, they are ideal for the manufacturing operations of products intended for consumption or direct contact with consumers, where unsanitary conditions can result in illness or injury. 316L stainless steel offers the corrosion resistance needed to prevent the contamination of process fluids.

By eliminating crevices and cavities from the valve design and achieving smooth, polished finishes on internal and external surfaces, we minimize the risk of material and bacteria buildup in our valves. We test 100% of our check valves before shipping them out to customers.

A DFT® DSV® Sanitary Check Valve Success

A major engineering firm contacted us on behalf of several pharmaceutical companies. The firm needed to find a check valve solution for their noncorrosive medical waste drain system. The check valve needed to operate at 20 psig or less with a flow of 3 GPM, have sanitary end connections, provide tight shutoff, have a low cracking pressure to open and be able to be steam cleaned in place.

The check valve had to withstand high temperatures, as the firm used 330°F steam to clean the entire medical waste process system 3 times a day. The valve also needed an extremely smooth finish to maintain sanitary conditions.

Responding to the challenge, a DFT® 2 inch DSV® vertical check valve was specified. Designed to prevent flow reversal, this non-slam, full-body valve came equipped with a 0.1-psi cracking pressure spring. We also designed it with tri-clamp connections for ease of disassembly. The product was so successful that… Get the full story in our eBook!

Upcoming Webinar: Severe Service Control Valves – Problems & Solutions

Maintaining the performance of your facility’s control valves will ensure continued successful operations for your organization. At DFT®, we know a thing or two about valves, and we’re excited to share our knowledge at our upcoming webinar about control valves on May 15, 2019 at 2:00 PM Eastern Standard Time.

During the webinar, we will discuss some of the common problems and solutions that develop in severe service valve equipment, and we’ll also explore a few issues that can lead to critical failure in your service control valves.

Talking Points and Topics

Some of the questions that we’ll answer in our webinar include:

• What is severe service?
• What are the different types of control valves?
• What types of service do they control?
• What is cavitation control?

We’ll also talk about our valves’ design features and how they handle the effects of cavitation and other wear and tear issues. We will provide an overview of the Bernoulli Principle, which states that decreases in pressure and potential energy lead to increases in the speed of a fluid—one of the basic principles by which valves operate today.

Finally, we’ll go in depth on how causes and effects of:

• Flashing and cavitation
• Providing required flow
• Actuation selection
• Achieving tight shutoff
• Slurries and erosion
• High-pressure applications
• High-temperature applications

After we finish our presentation, there will be a chance to discuss the topics covered as well as answer any questions you may have.

Benefits of the WLC® Wafer Style Silent Check Valve

Typically used to restrict fluid flow to a single direction, check valves play an integral role in all types of liquid networks. At DFT® Inc., we’ve been manufacturing top-quality check valves and control valves since 1943. The DFT® Model WLC® Wafer Style Check Valve, a spring-assisted, lightweight model, offers a number of unique advantages over traditional valves.

The dual/center-guided design improves stability, while the disc and seat arrangement ensure a tight shutoff, eliminating the risk of reverse leakage and, therefore, preventing potentially dangerous water hammer. In fact, these valves are ideal for use in systems with a high risk of water hammer. Offering consistent, reliable operation and ensuring low maintenance costs, the WLC® product line can be used for a wide range of pressure/temperature combinations, making these valves ideal for applications involving liquids, gases, and steam.

Wafer Style Check Valves

As mentioned, DFT®’s wafer style check valves are specifically designed to prevent water hammer and reverse flow. Take this recent project as an example:

One of our clients approached us for assistance with an application involving raw water intake; the valves they were using were causing water hammer, and they needed an alternative solution to ensure optimal operational efficiency and reduce the risk of costly maintenance needs and downtime. We replaced the valves with our WLC® models and later assessed the facility during a routine maintenance operation. The water hammer had been completely eliminated. Simply by switching to these check valves, the client was able to fix an issue they had been dealing with for years, significantly reducing the risk of mechanical failure and ensuring optimal cost efficiency.

The WLC® check valves are available in a variety of ASME classes, and can be utilized in pipes of different line sizes. These valves can also be manufactured with a range of different materials for various types of applications. DFT®’s WLC® models meet stringent industrial standards, such as MSS-SP 61(for seat leakage) and MSS 126 and API 594 (for face-to-face dimensions).

Water Hammer Webinar Recap

DFT® Inc.’s Vice President and General Manager Arie Bregman recently gave an in-depth, solutions-oriented presentation on water hammer — a common issue that can lead to devastating effects. Arie is an expert in the valve sector, with over 35 years in the valve industry, with companies such as Nibco, Jamesbury and Metso. Arie holds a Master of Science degree in Mechanical Engineering from Worcester Polytechnic Institute and is active in the Valve Manufacturers Association in the US, serving on the Education and Training and the Technical Committee and is also a member of the VMA Board of Directors.

Below, we’ve provided a brief recap of his comprehensive water hammer webinar, which covered the following topics:

Identifying Water Hammer
The first step to treating water hammer is, of course, properly identifying it. Loud sounds — a series of banging, clanging, or rattling noises — often alert operators to the first signs of an issue. Chances are you’ve probably heard the sound of water hammer in your pipes at home or at your plant without even realizing it.

Defining Water Hammer
The webinar also delved into the precise definition of this phenomenon: Water hammer is a hydraulic shock that occurs in a liquid piping system, often to devastating effect. Water hammer can cause gasketed joint and expansion joint failure, pipe wall crack and joint leaks, deformation of piping support systems, and many other issues, all of which can lead to high costs and increased downtime.

Preventing Water Hammer
Next, Arie discussed many people’s main concern — how to prevent water hammer and avoid the numerous problems it can cause.

Because water hammer is often only briefly touched upon in engineering schools, it’s critical to have an expert like DFT® available to answer questions and provide advice for your specific application. Working with an experienced, knowledgeable partner will make all the difference when dealing with water hammer, helping you to avoid unnecessary expenditures, downtime, and general stress.

At DFT®, we’ve been producing top-quality in-line check valves for over 70 years, helping businesses across all types of industries avoid water hammer. Our expert team has deep expertise in identifying, solving, and, most importantly, preventing check valve failures.
