OS&Y gate valve is used to regulate the flow of water to fire sprinkler systems.
The outside and interior are both coated with a superior fusion-bonded (thermosetting) powder epoxy that is nominally 10 mils thick.
Flats cast into the bottom of the valve body let it stand up straight when it’s being stored or put in place.
Mueller’s design has two thrust washers and has consistently shown to be stronger than cast stems.
Offers an exceptional level of bonnet sealing (4″ – 12″ sizes).
Mueller OS&Y Gate Valveprovides a bearing surface between the enclosed wedge and the inner epoxy coating, minimizing operating torque and improving valve service life.
The waterway’s bottom has no grooves or recesses which could gather silt or debris and weaken the seal.
Mueller a2361 allows for full-sized shell cutters to be used with plenty of room during tapping operations.
The T40 RattlerTM offers features often reserved for bigger multi-gas monitors, such as a large liquid crystal display (LCD), internal vibrating alarm, audible/visual alarms, and simple push-button control.
The T40 Rattler is a low-cost, maintenance-free single gas monitor designed to safeguard employees in harsh environments from deadly hydrogen sulphide or carbon monoxide gas exposure.
The monitor continually shows ambient CO or H2S measurements in PPM and notifies the user when gas quantities surpass the pre-defined low or high limits.
The T40 RattlerTM incorporates a proprietary flip-cap calibration adaptor and a peak/hold function that displays the highest measurement taken throughout a shift.
T40 Rattler H2S has more features like adjustable warning setpoints, calibration gas values, and a text-only display selectable by the user through a simple push button.
It uses only one “AA” battery (included) lasts up to 1,500 hours and has a two-year guarantee from the date of manufacturing.
