In Petroleum, chemical industry, metallurgy, electric power, textile, military industries manufacturing process, now widely use the throttling device for fluid flow measurement and control. Like standard orifice plate flow meters. Our company manufacture a variety of throttling device that conform to international standard ISO5167:2003 and national standard GB/T2624-2006. Also manufacture widely used special throttling device such as 1/4 circular nozzle, double orifice plate and segmental orifice plate, conical entrance orifice plate, venturi tube etc.
Our company sincerely according user requirements or user’s drawings to manufacture throttling device and accessories.

1. Standard orifice plate, pressure taps is carrier ring, see figure a
Figure a Structure of standard orifice plate with carrier ring
2. Standard orifice plate, pressure taps is flange taps, see Figure b
Tapping position should be at the flange of the cylindrical surface (straight hole) or the side of the face (slant hole), The centerline of pressure taps distance to downstream side or upstream is all 25.4mm. It has convenient installation, not easy jam, sewage to facilitate,

3. Hidden flange taps orifice plate, see figure c
Using standard concave and convex surface flange external circular hole drilling with compressive, convenient installation guide, orifice plate accurate positioning and advantages of concentricity.
