Feature of Globe Control Valves

‌Globe Control Valves‌ utilize linear motion to position the shutoff member relative to the seat surface. Featuring a spherical cavity around the port, these valves regulate process flow when paired with an actuator. Single-seat variants often employ cage, three-way, or fixed constructions to secure the seat ring, guide the spool, and define flow characteristics. The modular design allows easy internal replacement for flow adjustment, capacity reduction, noise attenuation, or cavitation mitigation.

Cast Trunnion Side Entry Ball Valve

Product Description:

main feature

1. Effortless operation: The ball is supported by upper and lower bearings, which reduces friction and eliminates the huge sealing load caused by the inlet pressure pushing the ball and the seal seat.

Excessive torque.

2. Reliable sealing performance: The PTFE single material sealing ring is embedded in the stainless steel valve seat. A spring is provided at the end of the metal valve seat to ensure sufficient pre-tightening force of the sealing ring. The valve

When the sealing surface wears during use, the valve continues to ensure good sealing performance under the action of the spring.

3. Fireproof structure: In order to prevent the polytetrafluoroethylene sealing ring from burning due to sudden heat or fire, resulting in larger leakage and fueling the fire, the ball and valve are

A fireproof sealing ring is set between the seats. When the sealing ring burns out, the valve seat sealing ring is quickly pushed onto the ball under the action of spring force, forming a metal-to-metal seal.

Sealing, achieving a certain degree of sealing effect. The fire resistance test meets the requirements of APl6FA and APl607 standards.

4. Automatic pressure relief function: When the stagnant medium pressure in the middle cavity of the valve rises abnormally and exceeds the pretightening force of the spring, the valve seat retreats away from the ball to achieve automatic pressure relief.

As a result, the valve seat automatically resets after pressure relief.

5. Drainage pipeline: Drainage holes are provided on the upper and lower sides of the valve body to check whether the valve seat is leaking. During operation, when the valve is fully open or fully closed, remove the middle chamber pressure

Force, the packing can be replaced directly; the residue in the middle cavity can be discharged, reducing the contamination of the valve by the medium.

Chief Features：

Compared with floating ball valve, when working, all the forces generated by the fluid pressure in front of the valve on the ball are transmitted to the bearing, which will not make the ball move towards the valve seat, so the valve seat will not bear excessive pressure.And the torque of trunnion ball valve is small, the valve seat deformation is small, the sealing performance is stable, and the service life is long, which is suitable for high-pressure and large-diameter occasions. Advanced spring pre-seat assembly with self-tightening feature realizes upstream sealing. Each valve has two seats, which can be sealed in each direction. Therefore, there is no flow restriction for installation, and it is bi-directional. The valve is generally installed horizontally.

Chief Features

The structure design of elastic sealing ring has been adopted for floating ball valves. This seat design features is a bigger sealing pressure ratio between the ring surface and the ball when medium pressure gets lower where the contacting area is smaller, thus the reliable seal is ensured.when the medium pressure gets higher, the contacting area between seat ring and ball becomes bigger as the sealing ring transforms elastically to under take the bigger force pushed by the medium without any damage.

ISO platform can be selected to facilitate the operation of the actuator

The valve meets NACE standard, fugitive emission function and fire test certification of API Spec 607

The valve seat is designed with two-way seal and low operating torque. All valves have built-in cavity relief devices to relieve pressure from the upstream seat and apply positive preload to ensure low pressure seal
