Benefits of OSY Gate Valve

Outside Screw and Yoke (OS&Y) Design

The stem is located outside the valve body and fixed by the yoke. The rotation of the stem drives the up-and-down movement of the gate.The threaded part of the stem is visible from the outside, so it is easy to judge the open or closed state of the gate.

Manual Operation

Usually, manual operation is done by a handwheel. By rotating the handwheel, you can control the movement of the stem and the gate.Manual operation is simple and reliable, suitable for occasions where manual control is required.

Reliable Sealing Performance

The gate and seat are usually sealed metal-to-metal, and some designs use elastic seals to improve sealing performance.When the gate is closed, the gate and seat are in close contact to form an effective seal to prevent fluid leakage.

Robust and Durable Structure

The body is usually made of durable materials such as cast iron, ductile iron, bronze, or stainless steel, which can withstand high pressure and harsh environments.

Easy to Maintain

Since the stem and threaded parts are outside, they are easy to check and lubricate daily, reducing maintenance difficulty.

Application of OSY Gate Valve

Power Plants
OS&Y gate valves are used to control the flow of fluids in and out of machinery and equipment. Controlling the flow of inlets and outlets helps to regulate the temperature and pressure of the steam.

Water and Wastewater Treatment
OS&Y gate valves are used to control the flow of water and wastewater in treatment plants. An example of OS&Y gate valves used in water treatment is metallic or non-metallic gate valves that isolate sections of pipelines. This isolation allows maintenance work to be done without affecting the overall operations.

Marine Industry
The marine industry widely uses marine bronze OS&Y gate valves. The reason for their wide usage is that bronze is corrosion-resistant. Thus making it a valuable choice for both marine and shipbuilding industries. The OS&Y gate valves are commonly found in seafaring vessels. The valves are used to control the intake and outflow of water from the ship's ballast system.

Oil and Gas Industry
In the oil and gas industries, OS&Y gate valves are used to control the flow of these fluids within pipelines, drilling, and production equipment. The industries use carbon steel OS&Y gate valves. Carbon steel is highly durable and can easily withstand the extreme pressures and temperatures that are often found in these environments.

HVAC Systems
These industries use OS&Y gate valves in their cooling towers, chillers, and piping systems. They control the flow of water and steam in the systems, thereby helping them to maintain the desired temperature and humidity levels.

Q: What is the difference between NRS and OS&Y gate valves?

A: NRS means Non-Rising Stem. OS&Y means Outside Stem and Yoke. In an NRS valve, the stem will turn to open and close the gate, but the stem does not move up or down as it turns. With a OS&Y valve, as the stem turns, it moves into or out of the valve, which also moves the gate to open or seal the valve.
