Brass Ball Valves (Couple-Collector) according to the Iranian National standard No. 16222 and is
made of hot forged brass. The main form of ribs is calculated in inches based on EN ISO-228
Standards.are usually used in building facilities, floor heating systems, warm and cold building
water supply networks. The valve is quarter-turn and opens and closes with a 90-degree rotation
of the handle. Internal and external surfaces are coated with nickel to avoid long-term corrosion
against minerals of water or other environmental corrosives. The ball inside the valves is covered
with chromium in addition to nickel to minimize its erosion due to friction with plastic tape.
The sealing angle of this type of valve is +15 degrees, the best sealing angle for ball valves.
A total of 100 % pressure tests are performed on all valves during a pre-defined period, and torque
tests and impact tests are performed randomly too.
