China Gate Valve Suppliers

A Gate Valve is a crucial shut-off Valve in pipeline systems, designed to control fluid flow by lifting a gate (or disc) to open or lower it to close the passage. It features a linear motion mechanism, where the gate moves perpendicular to the fluid flow direction, providing a full-bore opening when fully open, minimizing flow resistance. This design makes it ideal for applications requiring unobstructed flow, such as water supply, petroleum, and chemical pipelines.

Constructed from materials like cast iron, carbon steel, stainless steel, and brass, Gate Valves offer durability and corrosion resistance for diverse media. They come in Flange , threaded, or welded connections, with flange-type valves easily paired with a Flange Adaptor for compatibility with varying pipeline specifications.
In system integration, Gate Valves work with other components: a Bellow Expansion Joint handles thermal displacements near the valve, while a Rubber Expansion Joint absorbs vibrations, reducing stress. A Flexible Metal Hose adds routing flexibility around the valve. For maintenance, a Dismantling Joint simplifies access. When backflow prevention is needed, a Duckbill Check Valve installed downstream complements the Gate Valve’s shut-off function.

Gate Valves excel in on/off operations rather than throttling, as partial opening can cause erosion. Their robust design ensures long service life, making them essential in industrial, municipal, and commercial pipeline networks, ensuring reliable fluid control when paired with key system components.

Gate Valve

A gate valve is a valve that opens and closes by moving the opening and closing part (gate) in the direction perpendicular to the flow direction of the medium (channel axis). The gate stem of the gate valve moves in the direction perpendicular to the center line of the valve seat, so that the sealing surface of the gate valve plate fits, and the sealing effect is enhanced by the top wedge, spring or wedge shape of the gate valve, thereby preventing the medium from passing through. The opening and closing part of the gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid, so the gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.

Product Detail

The gate valve is mainly composed of valve body, valve cover, bracket, valve stem, valve stem nut, gate, valve seat, stuffing box, sealing packing, upper sealing seat, packing gland and transmission device.

Valve body: This is the main part of the gate valve, usually made of cast iron, cast steel, stainless steel or other alloy materials. There is a medium channel inside the valve body, in which the gate moves up and down to control the flow of the medium.

Valve cover: The valve cover is usually connected to the valve body by bolts, which is used to close the upper part of the valve body and protect the valve stem and other internal parts from the external environment.

Gate: The gate is the opening and closing part of the gate valve, which moves in a direction perpendicular to the flow direction of the medium. The gate has two sealing surfaces, which usually cooperate with the valve seat to form a seal. The gate can be rigid or elastic, depending on the design of the gate valve.

VOICE

WHAT A CLIENT SAY?

Customers' evaluation of gate valves is usually based on its performance, quality, reliability, service life, service and price. Many customers mentioned that the opening and closing operation of the gate valve is flexible and convenient, and can respond quickly to control needs. The sealing performance of the gate valve has been widely recognized. Customers believe that it can effectively prevent media leakage and ensure the safe and stable operation of the system. Customers generally reflect that the failure rate of the gate valve is low and it can maintain stable performance in long-term operation. The service life of the gate valve is long, which can meet the needs of long-term operation and reduce the frequency and cost of replacement.

FAQ

Important things you should know

What is the role of the gate valve?

Gate valves are the most common opening and closing valves, while butterfly valves refer to valves with a closing part as a disc, which mainly rotates around the valve shaft to achieve the opening and closing functions. It mainly plays the role of cutting off and throttling on the pipeline. The action mode, function and purpose are different.

How to install a gate valve?

1. The installation of gate valves generally includes cement pouring, bolt connection, welding and placement. 2. The installation must comply with the requirements of the drawings, and the construction should comply with the provisions of the construction documents. 3. Before installing the gate valve, all connection surfaces should be cleaned and all connection bolts should be checked for looseness. 4. When installing the gate valve, the gap between the gate body and the gate seat must be ensured to avoid water leakage or damage. 5. After installation, the gate body, gate seat, flange, etc. should be inspected and can only be used after the inspection is correct.

How to choose a gate valve?

First determine the purpose of the gate. For example, if we want to install the valve in front of the water meter to prevent water backflow, then we can choose to install a check valve. When selecting a valve, we also need to choose valves of different materials according to its working environment. For example, if the valve is installed outdoors, we can choose stainless steel valves with good corrosion resistance, etc.

Common faults and treatment methods?

1. Manual pressure relief valve leaks: Check whether the threads in the valve body are loose or damaged; check the aging or damage of the seals; check whether the packing seals are loose or damaged.
2. The manual pressure relief valve cannot be closed normally: Check whether the threads in the valve body are loose or damaged; check the aging or damage of the seals; check whether the packing seals are loose or damaged.
