Ball Valves

Known for its robust design, superior sealing areas, and stainless steel overlays, these ball valves enables full fluid flow with minimal pressure drop, making them ideal for handling viscous liquids. AYTC is widely recognized as the leader in providing valve solutions for the oil and gas industries' most severe service applications. These design features allow AYTC to provide valves with unmatched durability, safety and long-term performance.

Knife Edge Gate Valves

AYTC's Knife Edge Gate Valves are specially designed for tough applications. These valves features a single piece full port cast stainless steel fully lugged body which is very robust in construction to cater to extreme demanding applications and ensure greater flow capacity and minimal pressure drop. Our knife edge gate valves incorporate gates made of stainless steel and other superior alloys are ground with super surface finish on both sides to assure positive shutoff. The machined and highly finished gland pockets ensure a leak proof gland packing and perfect stem seal. AYTC's high performance knife edge gate valves are available in unidirectional / bi-directional design which provides better value and performance with many standard features which others lack.

Gate Valves

AYTC offers gate valves that are manufactured to the highest quality standards and will withstand the harsh environments of industries such as oil, gas, hydro power and chemical. Because of our indepth industry experience, AYTC gate valves are trusted and relied upon over competitor’s products. Our extensive product line is made up of pipeline gate, parallel slide gate, pressure seal gate, wedge gate, expanding gate, geothermal gates, and API 6A wellhead gates.

Globe Valves

Used primarily for regulating flow in a pipeline, AYTC globe valves are the top choice for oil, gas, chemical and hydropower industries because of their smooth operation and tested reliability. Globe valves have a spherical body that is internally separated by a baffle. The opening in the baffle forms the seat in which the disk (plug) is lowered into to close or shut the valve to stop the flow of fluids. The proportional relationship between the disk and the seat enables precision flow regulation. All AYTC globe valves provide leak-proof operation, resistance to harsh chemicals and environments, and extended life under frequent operation.

Safety Valves

Safety Valve is a one type of valve that automatically actuates when the pressure of inlet side of the valve increases to a predetermined pressure, to open the valve disc and discharge the fluid ( steam or gas ) ; and when the pressure decreases to the prescribed value, to close the valve disc again. Safety valve is so-called a final safety device which controls the pressure and discharges certain amount of fluid by itself without any electric power support. Safety Valves are mainly installed in chemical plants, electric power boilers, gas storage tanks to prevent the pressure vessel from exploding / damaging.

Check Valves

AYTC offers check valves that are manufactured using a hinged movable disk or gate that opens and closes in response to fluid. Our valves are designed for large industrial applications in the oil, gas, chemical, and hydroelectric power industries and can handle the pressures of these applications. For reliability, durability, and a partner in process engineering, trust in the experts at AYTC.

Butterfly Valve

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

Float Valve

AYTC offers noncorrosive, heavy duty, and high quality PVC float valves. These float valves are made of a high grade NSF rated PVC. These valves utilizes the latest materials for increased performance, reliability, and economy. AYTC's PVC float valves are the cost effective alternative to stainless steel and the noncorrosive alternative to a brass float valve.
