When space is tight but flow control is critical, Wafer Type Ball Valves offer the perfect balance of compact design, leak-proof shut-off, and easy installation. At Perfect Engineers, we manufacture and supply Wafer Style Ball Valves for HVAC, chemical, water treatment, food, pharma, and light-duty process pipelines where flange-less, weight-reduced, and space-saving designs are in demand.
These valves are designed to fit between flanges without the need for bolt holes on the valve body—making them easier to install, remove, and maintain in tight pipeline layouts.
A Wafer Type Ball Valve is a quarter-turn shut-off valve designed to be sandwiched between two pipe flanges using bolts through the flanges, not the valve body itself. These valves are:

Yes—many models offer full port flow to minimize pressure drop and maintain process efficiency.
Absolutely—all our wafer valves are ISO 5211 ready and can be fitted with electric or pneumatic actuators.
Most models are suitable for PN16 or Class 150. For higher pressures, use flanged or trunnion ball valves
Yes—provided you select metal-seated or graphite-packed options with appropriate pressure ratings.
