C113684 diaphragm kit is specifically designed for the EMERSON ASCO 353 series pulse jet dust collector valves. It is a great option if you're looking for something that offers great value for money. Using our SMCC diaphragm kit keeps the pulse valve working as well as it should, stops baghouse dust collectors from being out of action, and greatly reduces the cost of replacing diaphragms.
The pulse valve diaphragm is simple. When it is energised, air trapped above the diaphragm quickly escapes. This opens the main valve straight away. When the power is cut off, air slowly comes out through the relief port. This makes the pressure on both sides of the diaphragm the same, and it closes the valve straight away. This makes sure the dust collector works continuously and efficiently.



Q1: Is the C113684 diaphragm kit compatible with all EMERSON ASCO 353 Series pulse valves?
A1: The C113684 kit fits 2-inch and 2.5-inch pulse valves. Verify valve size before purchase to ensure perfect fit. For other specifications or series, refer to the order code chart below for reference.
Q2: How do I choose the right material (NBR/TPEE/FKM) for my pulse valve?
A2: The type of diaphragm material you need depends on the temperature.
- NBR: -10°C and 80°C.
- TPEE: -10°C and 100°C.
- FKM: -10°C to 200°C. Q3: Can the C113684 kit truly replace genuine EMERSON ASCO spare parts?
A3: It provides seamless replacement.
Q4: What does the one-year warranty for C113684 ?
A4: When used normally, the C113684 diaphragm kit can last for up to 1,000,000 blow cycles. The 1-year warranty covers manufacturing defects, material quality issues, and performance failures during normal use. Please note: the warranty does not cover damage caused by incorrect installation, misuse or normal wear and tear. If the diaphragm kits are breaked for nonhuman caused damage, we will resend them to you.
Q5: How do I install the C113684 replacement kit?
A5: Before you install it, turn off the power and air supply to the pulse valve. Then, make sure the valve body is clean and free of any debris. Follow these steps:
1. Take the pulse valve apart following the standard procedure (check the ASCO 353 Series Valve Manual if you need to).
2. Take out the old diaphragm and other parts that are worn out.
3. Fit the new diaphragm and spring from the C113684 kit, making sure they are lined up correctly and that there is a tight fit.
4. Put the pulse valve back together in the opposite order to taking it apart.
5. Connect the power and air supply, then test the valve to make sure it's working properly.

Q6: Where is the C113684 kit sold? How can I place an order?
A6: The C113684 kit is currently sold worldwide. Contact our sales team via email, phone, or online chat. We offer global shipping services. Bulk orders qualify for discounted pricing and customized logistics solutions.
Q7: What should I do if the pulse valve doesn't work properly after I install the C113684 kit?
A7: If the pulse valve doesn't work properly after it has been installed, first check the following:
1. Make sure you install it properly, so that it is not misaligned or damaged.
2. Make sure the operating temperature is the same as the selected diaphragm material.
3. Check that the air pressure is normal (usually 0.3-0.6MPa) and use clean, dry air to stop the vent holes getting blocked or the diaphragm getting damaged.
4. Check the electrical connections to make sure the pulse valve's power button works.
