NRA3-1/8 is an all-purpose, automatic, reed-style gas flow control valve. It is a self-acting precision pressure relief valve which is connected to a flow line and used to control the flow of gas through the line. The valve can be sometimes equipped with an integral check valve. This valve can also be used to maintain a controlled pressure in the pressure side by means of a pressure/vacuum switch.NRA3-1/8 is manufactured for a working pressure range of up to 150 PSI and a temperature range of -20°F to +160°F. It is an effective flow control device suitable for most and varied industrial applications. It is an automatic valve or regulator that is used to ensure that the pressure inside the system remains stable and does not exceed the set point by an excessive amount.The valve body of NRA3-1/8 is made of brass, stainless steel or nylon. The main spring in the valve controls the valve opening and closing by regulating the gas flow. The main spring is adjusted to the desired pressure simply by turning the adjustment knob on the spring housing or dial face. The set pressure is applied to the diaphragm via the adjustable spring by a long nut which provides the necessary pressure for the diaphragm to mechanically open and close the poppet.The operation principle and application field of NRA3-1/8 mainly depends on the diaphragm movement because of the spring that is created by the variable spring action. It consists of four major parts namely the diaphragm body, diaphragm seal, poppet valve and the main spring. The diaphragm body, Diaphragm seal and poppet valve are all made of stainless steel for superior corrosion resistance. The main spring is adjusted according to the desired pressure. NRA3-1/8is widely used in many types of industrial applications such as HVAC, medical, automotive, and general industrial applications. It provides an economical means of controlling gas flow for various industries. Since it is pressure regulated, it ensures a constant gas flow rate, which is necessary to maintain system balance and safeguard against the pressure rising beyond a certain level. It is also commonly used in commercial restaurant and kitchen equipment, such as coffee makers, gas boilers, coffee roasters, and dual fuel appliances.NRA3-1/8 is a valve often used for gas shut-off applications and pressure control. It can be used for all types of applications and is suitable for both liquid and gas services. It is also used as a pressure relief valve for pumps and compressors, as well as an air-vent valve for air blowers. It is further used in fire fighting, door control, cold storage, and other industrial applications.In conclusion, NRA3-1/8 is an ideal and reliable flow control valve because of its wide range of applications, working pressure range, and temperature range. It can be used in medical, automotive, commercial restaurant and kitchen equipment, and other diverse industrial applications. Its high quality and precision control make it the valve of choice for many valuable industrial controls.
