GATES

In METACOL within our main products we have the commercialization of GATES in HD; These are hydraulic or mechanical elements, whose function is the regulation of the transit of water or any other fluid in pipes, canals, dams, locks, bypass works, among other hydraulic structures. Guillotine Gate with HD Shutter AWWA C-513 / C-561 /C-563 Key points for the selection of our gates SELECTION The correct selection of a certain type of side gate depends on many factors: the maximum fluid pressure head, the type of fluid, the number of seals required, the type of seal required, the depth of the installation, the drive system, the operating position, available space, width, stem length (distance from the center of the gate to the upper point from actuator to maneuvering column). ACCESSORIES NECESSARY FOR STEM INSTALLATION: Made of stainless steel. They allow the operation of the gate acting as a screw. MANEUVERING COLUMN: It ensures stem guidance and gate operation from the maneuvering surface. GUIDE SUPPORT: In installation depths greater than 2 meters it is convenient to use guide supports that control and guide the movement of the stem. MAXIMUM OPERATING PRESSURE: The maximum operating pressure is 5 m.c.a. For higher working pressures, the METACOL technical department should be consulted beforehand.   SEAL TESTS: According to AWWA C-513 / C-561 / C-563 standard. PAINT COATING: According to AWWA C-550. OPERATION: An opening and closing cycle.   INSTALLATION You must take into account the following technical information: Assembly plan or installation according to the type of gate. Overall Plan of the Gate. [embed]https://www.tiktok.com/@metacol/video/7146323865277435142?is_copy_url=1&is_from_webapp=v1[/embed]

HYDRANTS

WET BARREL TRAFFIC HYDRANT

In METACOL within our main products we have the commercialization of HYDRANTS; Popularly known as fire hydrants, they are hydraulic devices, connected to a water supply network, intended to supply water in case of fire. General aspects of our products: Product Manufacturing according to Resolution 0501 of August 4, 2017 / Ministry of Housing, City and Territory. Norm: AWWA C-503 / C-502 Features The hydrant consists of two bodies, its seal is located on the lower elbow ensuring that, at the time of a vehicular collision with the breakage of the fuse screws of the flanged union between bodies, the closure of the hydrant is maintained in the buried body in order to control the fluid. The color of the upper body is manufactured according to the requested flow rate.

Nominal diameter: DN 4"(100 mm) - 6"(150 mm) WORKING PRESSURE 200 PSI For higher working pressures, the METACOL technical department should be consulted beforehand. EXTREME CONDITIONS OF USE 

• Continuous pressures above the recommended pressures can cause the product to not operate properly.
• Prolonged exposure to the elements (sun's rays) affect the color of the coating.

ESTIMATED SERVICE LIFE The products manufactured by METACOL have an estimated useful life of 15 years, when all the specifications and recommendations for use, installation and maintenance of the product contained in the company's technical information are met. RECOMMENDED USE   In nominal diameter of 4" (100mm) and 6" (150mm) with two outputs of 21/2" and an outlet of 41/2" with flow rates up to 1,000 gpm. Maintenance

• Operate the hydrant's main valve at least three times a year with an opening and closing cycle.
• In case of leakage by the seal of the stem, the O'Rings on top must be replaced.
• If the hydrant leaks in its seal, the condition of the seat and shutter should be checked, which must not present breakdowns or scratches.
• In case of damage to the seal, the seat and / or the shutter of the hydrant must be replaced.

VALVES

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) [gallery ids="1077,1078,1079,1080"] 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. [playlist type="video" ids="1082"]
