To support the gas produced by our company, we stock regulators and valves as supporting facilities for our standard gases and high purity gases. Including:
1.Regulators:
Brass Regulator: It is made of good brass, which is mainly preferable for noncorrosive calibration gases or high pure gases. Gas is delivered to equipments through the gas regulator. It is also used to adjust the pressure of chromatographic carrier-gas. Main models are as follows:
Model No. Gas Service Inlet Gauge (Mpa) Qutlet Gauge (Mpa) Max Inlet Pressure (Mpa) Delivery Pressure (Mpa)
352X-175 O2 25 2.5 15 0.03~1.2
352Y-20 C2H2 4 0.25 3 0.01~0.15
352F-20 C3H8
LPG
4 0.25 3 0.01~0.15
190H-80 H2 25 1 15 0.02~0.56
1901N-80 Ar  N2  He 25 1 15 0.02~0.56
191A-25L Ar (flowmeter) 25 Outlet Flowmeter 0~25 L/min LPM Ar
Input Voltage 220VAC190w
Stainless Steel Regulator: It adopts 316L stainless steel material and its membrane adopts PTFE or double-layer rubber structure so that the regulator has stable chemical properties. And it is mainly preferable for calibration gases, high pure gases and corrosive gases such as NH3, BCl3, HCl, H2S, SO2.
Two Stage Regulator: It adopts two-stage membrane decompressed structure, which ensures its output to keep invariable when the pressure of cylinder goes down, thus it is more preferable in situations which have precise requirements for pressure and flow, such as gas welding and cutting, industrial manufacture, laboratory testing, etc.
2.Valves:
Various industrial gas cylinder valves: There are brass cylinder valves made of good brass and stainless steel cylinder valves made of 316L material. The inner of valves adopts sealed membrane structure, which have little effect for gas medium. They are suitable for calibration gases and high pure gases, therein corrosive gases need to use stainless steel valves. The models are: QF-2, QF-90, QF-30, QF-90A, PX-32, QF-011, QF-10, QF-2A, QF-2A1, QF-11C etc.
Diaphragm Shut-off Valves: They are suitable for various of high pure, clean, flammable, poisonous and corrosive gases, as well as vacuum system. Their features are: with no gasket material, composited and pressurized with 316L stainless steel metal membrane, secure and reliable structure, small inner volume, long service life, and no pollution.
Needle Throttle and Needle Shut-off Valves: They are suitable for the fields of petro-chemical industry, instruments and experimental equipments. They make use of a pole which can move or turn in the sealed gasket material to adjust or cut the airflow.
Connections: We have various connections attached to valves, such as Jaket pipe connections, metal-metal flat sealed connections and BS connections etc, which are used to connect the regulators.
