Large Size 2"-36" Inch Cast Steel Flanged End Flexible Wedge Gate Valve
Gate Valves
TEKO Valves are a professional manufactuer of industrial gate valves in different materials such as: bronze, iron, stainless steel and cast steel. TEKO Valves offers Gate Valves in two different forms, parallel and wedge-shaped. Parallel Gate Valves are used to control the flow pressure while Wedge-Shaped Gate Valves are most commonly used and allow for fluids to be tightly shut off.
How does a gate valve work?
Gate valves are designed to turn the flow of a liquid on or off by restricting or opening the flow with a round or rectangular wedge. Gate Valves can also control the pressure of liquid flow through pipes or valves.
Features
* Industries Steel Gate Valves have been designed to meet the requirements of API 600 / BS 1414 / API 603 / API 6D /ASME B 16.34
* Face to Face and End to End dimensions conform to ASME B 16.10 /BS 2080 / DIN
* End flange dimensions conform to ASME B 16.5 / API 605 / BS 3293 / DIN
* Butt weld end dimensions conform to ASME B 16.25
* The stem nut design allows for the removal of the hand-wheel while keeping the Stem and Gate in a fixed position.
* Anti-frictional Ball bearings are provided in Larger sizes and classes.
* The strength of Stem to Gate connection is stronger than the strength of the Stem at the root of the operating thread
* Outside screw and yoke construction
* All the valves provided with backseat arrangement
* The gland is of self-aligning two piece type Deep stuffing box
* Body ports are streamlined, permitting unobstructed flow, reduces turbulence, results in lower pressure drop & lower erosion
* The Seat-rings are cylindrical bottom seated type having ample cross section for strength are provided with welded in. In case of SS valves, the Seat-rings are integral to Body
* The Body to Bonnet joint is flat in ASME 150# valves, a male and female joint is used in 300# & 600# and ring joint is used in higher pressure rating
* Valves meet the requirements of fugitive emission levels Shell category B as per MESC SPE 77
