Product overview
EF-1 type two valve group is our company in the absorption of the United Kingdom, the United States, Japan, Singapore and other countries in recent years on the basis of the instrument valve group structure, with a small structure, beautiful appearance, reliable performance, easy to use flexible, standardized, high degree of universality. The valve integrates the three devices of cutting off, calibration and exhaust, and can be connected with the transmitter through the flange, and the structure is small, reducing the leakage of joints. The valve has two concave joints, which can be used for the installation of pressure gauges, pressure sensors or pressure switches. This series of valve sets can be used in various pneumatic or electric differential pressure (pressure) transmitters at home and abroad.
