True Union Diaphragm Valve

The Hayward Flow Control DAB1007UFF is a manual two-way diaphragm valve built for chemical media. Its PVC body and FKM diaphragms meet ASTM D1784 standards and carry a maximum operating pressure of 150 psi and a maximum operating temperature of 140 degrees F. The True Union design combines an NPT connection on one side with a socket connection on the other for versatile piping.

Chemical Process Installations

This valve suits plants and OEM systems that need reliable shut-off for aggressive fluids at moderate pressure and temperature. The wheel handle and position indicator give clear visual status during operation. Installations requiring automated actuation, higher pressure ratings, or larger nominal sizes should select a different model.

3/4 Inch Nominal Valve Size

The 3/4 inch nominal size and 4.72 inch overall length determine whether the valve fits the existing pipework and available space. Coefficient of volume (Cv) 8 defines the flow capacity for system sizing calculations. Confirm these dimensions against your layout before ordering.

Questions about this item

How do I verify the valve is functioning correctly after installation?

Check that the wheel handle moves smoothly from fully open to fully closed and that the position indicator aligns with each setting; then confirm no leaks appear at the NPT and socket connections while the system runs at up to 150 psi and 140 °F.

What comes in the box and what must I supply myself?

The valve body, FKM diaphragm, FKM seals, wheel handle and position indicator are included; you must provide the 3/4 in NPT pipe thread sealant or tape for the threaded side and PVC solvent cement for the socket side.

Which version of this diaphragm valve should I choose for my chemical line?

Select the DAB1007UFF model with PVC body, FKM diaphragm and FKM seals when your media requires ASTM D1784-rated PVC compatibility and a 150 psi, 140 °F operating envelope.
