Gate valves are useable in water utilities industry, water supply networks, irrigation systems, petroleum, oil and gasoline networks, tanker manufacturing industries, pneumatic and hydraulic industries, chemical materials and building industries.
The gate valve is designed and manufactured according to Iranian National Standard No. 3664 and is made of forged brass. The main form of ribs is calculated in inches based on EN ISO-228 Standard. Intermolecular distance is reduced as less as possible in production method to increase body resistance in destruction tests; consequently, working pressure resistance rises. For this reason, forging method is selected.
Advantages
Mounting two (2) O-rings of NBR Material on the stems of the gate valves, will not only assist the sealing of the hexagon nut under- zone but also increase sealing of the plug outer side several times as much. As a result, it is not necessary to regulate the hexagon nut required for sealing extending.
