OPTION DEFINITION FOR TABLE 6
Dome Loaded - (0)
The dome loaded option allows for regulators to be loaded from remote location to change pressure settings. NOTES:Diaphragm failure will result in loading fluid to mix with the process being controlled. Maximum Loading Pressure is 125 psig (8.6 Barg).OPTION DEFINITION FOR TABLE 9
Captured Vent - (6)
The captured vent feature can be installed on any Sensiflo regulator. The design is for maximum safety for the user when handling toxic or hazardous media. The user can easily pipe this vent to a safe location. It features a 1/8” FNPT port located on the spring housing. This feature can be incorporated into a self-relieving regulator that provides an additional port to permit the piping away of the expelled media.
Cleaned for Oxygen Service - (M)This is a requirement for gaseous oxygen environments. All regulators requiring advanced cleaning shall be processed according to strict guidelines.
Mounting Bracket - (5)
The mounting bracket is a base, or step type. The material is 303 stainless steel. The bracket mounts to the back of the single stage, and back pressure regulators, via 10/32 screws.
Panel Mount - (C)
The panel mount feature requires a panel cut out of 1–3/8”, complete with a threaded spring housing, and a panel mount ring to secure the regulator.
Relief Valve - (H, J, K, or L)
The relief valve main function is to relieve excess downstream pressure due to system malfunctions. This feature prevents over pressurization by automatically venting of gas or liquid. The valve is fully adjustable, is 1/4” male x 1/4” male.
Self-Relieving - (S)
The self-relieving option features an integral mechanism allowing downstream pressure to be vented to atmosphere as the outlet pressure setting is decreased. This allows the user to easily and rapidly decrease the pressure in a closed, or low volume system without an auxiliary bleed valve. In addition, this option also functions as a sensitive relief valve.The pressure at which it relieves is automatically determined by the outlet pressure setting of the regulator.
Self-Relieving & Mechanical Stop - (T)
Same as self-relieving except construction includes mechanical stop to limit maximum outlet setting.
Tamper Proof - (1)
In this feature the control knob is removed and replaced with an acorn nut. The user can set the outlet pressure and securely tighten the nut, preventing any unwanted adjustments on the regulator.
Colored Knobs - (2, 8, 9 and W)
In this feature the control knob is anodized aluminum either in black, blue, green or red, compared to the standard red composite knob. This allows for color coding of processes.
Vacuum Assist Spring - (V)
In this feature a vacuum assist spring is placed under the diaphragm. This spring prevents the diaphragm from collapsing during a vacuum purge.
