| Checked orifices are a series arrangement of a precision orifice, a ball check valve and an optional screen. The all metal assemblies are made of brass or stainless steel. Gas... | |
| These checked orifices consist of a precision orifice in a series with a ball check valve. The flow rate of the restricted flow is set by the orifice size. Reverse... | |
| Bidirectional fixed flow orifices provide metered flow in two opposite directions. Flow in one direction occurs only through the low flow orifice. Flow in the opposite direction occurs through both... | |
| Orifices are accurately machined, thoroughly cleaned, and flow tested to exacting standards. Sizes range from .004" to as large as .063" orifice diameter dependent on fitting geometry. Special sizes can... | |
| These low cost flow controls employ a check valve with a stainless steel or buna-N ball and a precision orifice. Free flow occurs in one direction and metered flow occurs... |
