The sanitary clamp butterfly valve is generally used in the food and brewing industries where there is a need for CIP/SIP, as well as in situations where the seal needs to be replaced periodically. It is easy to dismantle without the wear and tear that affects the effectiveness of use when dismantling multiple times, as is the case with the threaded type. Unlike the welded type, it is not difficult to dismantle once installed, which can cause delays in the work schedule.
In terms of operation, Sanitary Butterfly Valve Clamp End With Pull Handle will be simpler to use. From the point of view of control precision, Sanitary Butterfly Valve Clamp End With Gripper Handle provides you with more control angles, that is, you can adjust the flow rate by adjusting the gripper to different positions. If you have a high flow rate, the gripper end is more suitable.
It is important to note that the Sanitary Clamp Butterfly Valve is not suitable for high pressures. It is very prone to leakage or even dislodgement due to high pressure, which will not only cause contamination to your product but also delay the work schedule. For corrosive media, there are also safety risks.
The specific working temperature depends on the material of the sealing ring used in the sanitary clamp butterfly valve. Generally speaking, the operating temperature range of sanitary clamp butterfly valves using EPDM as sealing material is -20℃-135℃, while the temperature range of FPM sealing material is -30℃-230℃.
The 3A standard is a hygienic code specifically developed for the food and dairy sector. Passing the 3A test means that you can trust your choice of sanitary clamp butterfly valve in terms of surface smoothness, material safety, cleanability and more. It will not deteriorate during subsequent use and sterilization or retain bacteria.
You need to carry out regular inspections of your sanitary clamp butterfly valve in order to detect problems in time. If you find any of the following problems with your valve, it needs to be replaced immediately:
- Leaks in the valve
- Deformation and discoloration of the seals
- Excessive use
In fact, regular inspection or replacement of the seals can effectively extend the overall life of the valve.
Our wafer-style butterfly valves follow 3A /SMS/DIN/ISO face-to-face dimensions. For weld-end configurations, overall length varies by size and pressure rating. Contact our engineering team with your specific size requirements — we provide detailed dimensional drawings for piping layout verification before order confirmation.
Standard butterfly valves: 15-20 working days for up to 100 pieces. For project quantities (100-500 pieces), 20-40 working days. We recommend placing project orders 4-6 weeks before the installation date to secure a production slot and ensure on-time delivery for your construction schedule
What Is a Sanitary Clamp Butterfly Valve?
A sanitary clamp type butterfly valve is a kind of butterfly valve fixed through the clamp and positioning bolts, and the sealing effect is achieved by the sealing ring(FPM/EPDM) to prevent media leakage. Compared with threaded and welded butterfly valves, this type of installation is more rapid and supports high-frequency disassembly and cleaning.
How Does a Sanitary Clamp Butterfly Valve Work?
A sanitary clamp butterfly valve is a valve body in which the opening and closing of the valve is controlled by the rotation of a metal piece (butterfly plate). When the angle of the rotating handle is in the 90° position, the butterfly plate will open or close completely, thus realizing the control of liquid flow.
How to Install a Sanitary Clamp Butterfly Valve?
Pre-Installation Check
Pre-installation check is a very necessary step, you should first confirm that the parts of the sanitary clamp butterfly valve are complete and undamaged. Next, you need to check whether the valve and pipe connections are clean enough and free of foreign matter or dirt, which will also affect the sealing effect after installation.
Confirm The Installation Position
What you need to confirm during installation is the alignment of the sanitary clamp butterfly valve with the pipeline, and at the same time the two flanges of the valve also need to be aligned. Because improper alignment may lead to uneven force on both sides, resulting in leakage problems in subsequent use. When the alignment step is completed, the sealing ring can be installed.
Fixing The Clamp
When fixing the clamp, you need to put the clamp over the outer side of the metal flap to fix it, and realize the fixing and sealing by tightening the nut of the clamp. In this step, you need to be careful to make sure that the tightness is appropriate. This is because tightening it too loosely can cause leaks, while over tightening it may cause damage to the part or even allow the sealant to enter the inside of the pipe, instead creating conditions for bacteria to grow.
Clamp vs Thread vs Welded Sanitary Butterfly Valve
| Features / Types | Sanitary Clamp Butterfly Valve | Sanitary Thread Butterfly Valve | Sanitary Welded Butterfly Valve |
| Installation Methods | Fixed by the clamps | Tightening by rotating the threads | High-temperature welding fixation |
| Sealing Effect | Mainly relies on seals (EPDM/FDP) for sealing
| Threads tighten better, but wear affects the sealing effect | Stronger overall seal after welding |
| Pressure Resistance | For low to medium-pressure fluids | Medium pressure | Suitable for higher-pressure fluids |
| Applications | Applications that require frequent disassembly, cleaning, and sterilization, such as food, pharmaceuticals, etc. | Suitable for small-diameter pipes | Large-diameter, high-pressure piping systems |
Tips To Choose The Suitable Sanitary Clamp Butterfly Valves
Selecting the Right Size
You first need to make sure that the sanitary clamp butterfly valve you select is the right size for your piping system. If the valve you choose is manufactured according to the 3A standard, its size is generally categorized as 1”, 2”, etc. Of course, you also need to check whether the manufacturing standard is the same (DIN/SMS/ISO, etc.), and choose the matching product.
Choosing Proper Sealing Material
Seals are also an important component of sanitary clamp butterfly valves, affecting the overall sealing effect. Simply speaking, EPDM supports high-temperature vapor cleaning and alkaline environments, while FPM is superior in corrosion and heat resistance. Of course, whether it’s EPDM or FPM, you’ll need to make sure they are FDA-compliant, which represents their safety compliance and better safety in food and drug production.
