The ROOTS B34 and B34S series regulators are essential components in various commercial and industrial applications, ensuring efficient and reliable gas flow management. These regulators are particularly well-suited for mid-range applications where rapid response to quick on/off loads is crucial.
Overview of the B34 and B34S Regulators
B34 Series Regulator
Appropriate for many commercial and industrial uses such as gas engines, burners, furnaces and boilers. The rapid response of the B34 is particularly well-suited for mid-range applications where quick on/off loads cause shock problems.
Model Variations:
- B34R: The B34R is the internal relief version of the B34 series. This model features an adjustable loading ring for controlled boost at higher flows and a 1″ internal relief valve.
- B34N: The B34N is a spring-loaded, self-operated regulator with no internal relief, an adjustable loading ring for controlled boost at higher flows, and a precision breather opening to ensure proper stability for all conditions. This regulator can be used on low or intermediate inlet pressures where an internal relief or other type of over-pressure protection device is not required.
- B34IMR: The B34 IM regulator is a single valve body regulator with built-in monitor operation. It features the safety advantage of a second gas tight lock-up seat if the normal orifice face and valve seat fail to produce bubble tight lock up. Designed specifically to comply with DOT OPS 192.197 paragraph B.
- B34MN: The B34MN is a non-relief type monitor regulator equipped with a closed-throat, downstream control line and an O-ring seal on the valve body stem through the throat to assure positive downstream control when installed ahead of a downstream regulator. Used in a series monitoring installation as the upstream regulator, this unit gives customers an operating device that assumes control over an operating regulator when failure is sensed by the control line of the monitor. This series system assures maximum safety with uninterrupted service. The monitor regulator is set to take over control from the operating regulator with only a slight increase in outlet pressure.
- B34MR: The B34MR is the same as the B34MN, except it has internal relief similar to the B34R.
Key Features:
- Interchangeable brass orifice
- 78 in2 of diaphragm area
- Spring-loaded internal relief valve assembly
- Field interchangeable adjustment spring
- Controlled size breather orifice eliminates pulsation and provides normal action at low flows
- Wide range of valve body sizes including NPT and flange connections
Benefits:
- ANSI Z21.80/CSA 6.22 certified
- Economical
- Protects equipment from shock damage
- Large 12″ diaphragm for better outlet pressure control
- Unmatched overpressure protection with internal monitor (IM) plus internal relief option
B34S Regulator
The B34S is a spring-loaded, self-operated regulator available with or without internal relief. It combines a robust design with economical solutions for mid-range commercial and industrial applications. Key attributes include an adjustable loading ring for controlled boost at high flows, a precision breather opening for stability, and, in the R model, a high-capacity internal relief valve. All critical components are made of durable materials like steel and aluminum.
Model Variations:
- B34SN: This version lacks an internal relief valve, making it suitable for applications where external over-pressure protection is provided.
- B34SR: Features an internal relief valve with a 1″ vent, providing additional safety for systems requiring internal pressure relief.
Key Features:
- Interchangeable brass orifice
- 27 in² diaphragm area
- Molded diaphragm of Buna-N and nylon
- Stainless steel and zinc-plated steel components for durability
- Multiple vent sizes (1/4″, 3/8″, 3/4″, and 1″)
- Die-cast aluminum seal cap
- Field interchangeable adjustment spring
- Upper diaphragm plate of plated steel
- Stainless steel lever pin
- Zinc with dichromate plated steel lever
- One piece molded Buna-N valve seat
- Alodined aluminum valve stem
- Delrin® vent valve with Buna-N seat
- Spring-loaded internal relief valve assembly
- Vent Sizes: 1/4″, 3 /8″, 3/4″, and 1″
- Stainless steel vent screen
- Controlled size breather orifice eliminates pulsation and provides normal action at low flows
- Wide range of valve body sizes including NPT and flange connections
Benefits:
- ANSI Z21.80/CSA 6.22 Certified
- Economical and space-saving design
- Protects equipment from shock damage
- Delivers commercial performance in a compact size
