Cost Effective Alternative to Expensive Diaphragm Seals

Winters’ (Canada) D10 Series diaphragm seals are cost effective alternatives to more expensive stainless steel or carbon steel diaphragm seals. When a customer has a lower pressure application (from vacuum up to and including 200 psi), the D10 Series may be an excellent choice for the customer.

With a body made from PVC (polyvinyl chloride) and a diaphragm made from Teflon, the D10 Series is compatible with many different types of process media. In some cases, such as in chlorine/water media, the Teflon diaphragm of Winters’ D10 Series is even superior to 316 SS, which can corrode from exposure to chlorine.

The D10 diaphragm seal has a gauge connection of 1/4” female NPT and a choice of 1/4” and 1/2” female NPT process connection. A diaphragm seal is a device consisting of a diaphragm welded (or firmly clamped) between two suitable flanges and properly gasketed to prevent leakage of liquid or gas.

The diaphragm is a dividing membrane or thin partition that acts as a barrier to a liquid or gas that may clog or corrode the sensing element of a pressure instrument.
