Watson McDaniel OSS-12-N-14-S TWMOSS12N14S

The OSS Series direct operated pressure regulators with heavy-duty stainless steel bodies are suitable for a wide range of applications in the low to moderate flow range. Applications include small heaters, humidifiers, various hospital equipment, tire molds, as well as many other general uses. The stainless steel body and trim also make this valve a consideration for potable water service. This style of regulator does not require an external sensing line. Set pressure is controlled by turning an adjustment screw with lock nut that increases or decreases spring force above the diaphragm. Several spring ranges are available, depending upon the downstream pressure that needs to be maintained. OSS Series contains hardened stainless steel seat and disc for extended service life (soft seat options available). Stainless steel diaphragms are offered for steam service. FKM diaphragms are specifically designed for water, air, gases and other liquid service and have a working temperature range up to 300 deg F.
