Construction: Rising stem gate valves consist of a valve body, a gate or disc, a stem, and a bonnet. The gate or disc is connected to the stem, which rises or falls as the valve is operated.
Linear Motion
The stem of a rising stem gate valve moves in a linear, vertical direction as the valve is opened or closed. This linear motion provides a visual indication of the valve position, as the stem is fully extended (upward position) when the valve is open and fully retracted (downward position) when the valve is closed.
External Stem Thread
The stem of a rising stem gate valve has its threading external to the valve body. This means that when the handwheel or actuator is rotated, it engages with a nut located within the bonnet, causing the stem to rise or lower.
Pressure Drop
When a rising stem gate valve is fully open, the gate or disc is completely removed from the flow path, resulting in minimal pressure drop across the valve. This feature makes rising stem gate valves suitable for applications where pressure loss needs to be minimized.
Installation Height
One consideration with rising stem gate valves is the required installation height. Due to the design of the external stem thread, a larger installation height is typically needed compared to non-rising stem gate valves. This should be taken into account when planning the installation and ensuring sufficient space.
Lubrication
Rising stem gate valves often have the advantage of easy lubrication. The exposed stem threading allows for the convenient application of lubricants, ensuring smooth operation and reducing wear and friction between the stem and other valve components.
Features
Efficient Stem Design
The valve incorporates a rolled stem design, enabling low operating torque values for smooth operation.
Versatile Ring Construction
We offer various alternatives for ring assembly, including pressed-in, threaded, or welded rings.
Accessory Options
Upon request, we can equip the valve with gearbox and actuator accessories to meet specific requirements.
Customizable Wedge Guide
For certain sizes, we provide an optional wedge guide as per customer request to enhance valve operation.
Additional Configurations
Specific sizes also allow optional additions such as a jacking screw, wedge stop, or drain plug upon request.
Optional Bypass Valve
For larger sizes, an optional bypass valve can be added on demand to facilitate streamlined operation.
Daily Maintenance and Care of the Rising stem gate valve
To ensure the normal use and prolong the service life of the Open-stem gate valve, regular maintenance and care are required. Here are some suggestions:
Regular inspection
Regularly inspect the Rising stem gate valve, including the valve stem, valve disc, seals, and other components for integrity and flexibility.
Cleaning and maintenance
Clean the valve to remove accumulated impurities and dirt, keeping the valve clean and smooth.
Lubrication treatment
Lubricate moving parts like the valve stem to reduce friction and wear, extending the service life of the valve.
Timely repair
Once a fault or abnormal situation is found with the valve, promptly repair and replace the parts to avoid affecting the normal use of the valve.

Key Components
Rising stem gate valves have parts that work together to manage fluid:
Gate
Blocks or lets fluid flow through.
Stem
Connects the gate to the handwheel or actuator. It moves up or down.
Body
Holds the parts and handles pressure.
Seat
Seals tightly when the gate is closed.
Packing
Stops leaks around the stem.
