Gate valves are used when the requirements are: low flow resistance, simple design, high capacity, low cost and hermetic closing. The main features of gate valves are the sealing surfaces between the gate and seats. The valve seats may form a wedge shape or be parallel. Gate valves are primarily used to permit or prevent the flow of liquids.
Why AMPO POYAM VALVES?Because we have been designing and manufacturing gate valves for almost 50 years. This has lead, without a doubt, to a design and production process that is top of the range in quality, reliability and effective sealing. Up to 72 inch valves are available in the production range and small valve manufacture is still very competitive due to AMPO process improvements and productivity.
The gate valves manufactured by AMPO include: rising stem, outside screw and yoke design and flexible wedge design.
Any other design parameters required by our customers may be adapted by our engineering teams. This flexibility enables us to be a market leader in special applications and valve requirements.
