(K) FJ41Y throttle shut-off vent valve

Uses

This product is a new generation of multi-functional throttle and shut-off venting valve developed on the basis of absorbing the advanced technology of throttle valve, globe valve and similar products at home and abroad, which has the characteristics of reliable sealing, erosion resistance, low noise, long service life and high degree of generalization, and is widely used in flow regulation, shut-off and venting of oil, natural gas and chemical pipelines.

Performance characteristics

The new soft and hard double sealing pair structure ensures reliable sealing; The spool, seat and cage sleeve are treated with a special process to resist erosion, wear and tear, H2S corrosion, and have a service life of up to 30 years. The throttling part of the valve adopts a symmetrical throttling structure, which can fully reduce the airflow noise during venting; High-performance combined slip rings are used between the valve core and the cage sleeve, so that the opening torque of the valve is very small; The unique design of the deflector wing on the valve body can eliminate the formation of eddy currents and collisions outside the valve jacket, which can cause vibration and energy loss. The transmission part is connected by steel balls so that the valve stem only does lifting movement in the process of opening and closing, there is no relative rotation between the valve core and the cage sleeve during operation, and there is no relative movement between the sealing surfaces at the moment the valve is closed, which reduces the wear between the sealing pairs and prevents the abrasion between the sealing pairs; The valve stem and bonnet are equipped with an upper sealing structure, and a triple seal with 0-ring and V-type seal packing is filled with sealing grease. When the valve is fully open, the packing is protected from erosion and erosion; Prolong the service life of the packing, prevent the leakage of the medium, safer and more reliable; The top-mounted spool, seat, and cage sleeve design can realize online maintenance of the equipment.
