VALVE ELASTIC GATE UP STEM

In METACOL we have a wide variety of valves, today we will tell you about our ELASTIC GATE VALVE ASCENDING STEM; The purpose of the gate valves is to stop or completely resume a fluid, they open and close the circuit by means of a disc that is gradually closed vertically until it adapts to the seat. They are bidirectional and integral passage so they offer a minimum loss of load. The gate valves are manufactured in cast iron or forging and in different materials: Bronze (especially to work with seawater), carbon steel, stainless steel (petrochemical sector), iron, forged steel or brass. The gate valves have an ergonomic design, easily accessible.Discs can be a solid or flexible wedge. Floppy disks were developed to overcome cooling adherence in high-temperature service and minimize operating torque. DN 2" (50 mm) – 20" (500 mm) AWWA C – 515/ C – 509 or ISO 7259 ENDS: ANSI FLANGE B 16.1 – ISO 2531 (ISO 7005-2)

RECOMMENDED USE Drinking water management with temperatures up to 60°C and service pressure up to 200PSI in overhead or surface networks. CHARACTERISTICS The design of this valve is solid wedge in ductile iron ASTM A-536 with total coating in elastomer. The seal on the valve stem is made through graphite rings compressed by means of the tow press. APPLICATIONS Fire fighting systems, industrial plants, hydraulic control stations, by-pass of regulating stations and control valves where it is essential to identify through the position of the stem the state of the valve open or closed). WORKING PRESSURE 200 PSI For higher working pressures, the METACOL technical department should be consulted beforehand. TESTS: HYDROSTATIC AND SEAL According to AWWA C-500 standard. ADHESION of the elastomer to the metal substrate according to ASTM D-429 standard. PAINT COATING According to AWWA C-550. MAINTENANCE Operate the valve at least three times a year with a full opening and closing cycle at the operating pressure. In case of any leak in the stem seal, the tows must be adjusted without altering the operating torque of the valve too much.
