| In order to minimize the impact of cavitation, the valve disc is made of cavitation-resistant materials (such as alloy steel) and made into a streamlined cone, and its angle is generally 140 to 180 degrees. Such a design can not only reduce cavitation, but also make the valve disc have a larger opening height, and generally will not throttle under small gaps. In addition, the sealing surface of the throttle valve L61H-40 is made of special materials and designs to improve its wear resistance and sealing performance. |

| Product Features 1. This valve is a new type of throttling, shut-off and venting product. The valve adopts cage-shaped fan leg throttling, has multi-stage throttling effect, obvious throttling effect, reliable sealing, convenient operation and maintenance, etc. 2. The valve adopts double sealing (hard and soft sealing) to make the sealing reliable, the carbide cover can be more resistant to air flow erosion and wear, and the double sealing can achieve zero leakage under high-pressure gas medium conditions. Long service life of the valve 3. The sealing surface of the valve seat adopts a conical seal, which is conducive to the valve itself to clean the dirt attached to the sealing surface 4. A balance hole is set on the valve disc of the valve, and the piston seal is easy and flexible to open, and the opening and closing torque is small 5. The throttling stop vent valve and the double-acting throttling valve have both throttling and cut-off (the seal is zero leakage) functions. The throttling part is separated from the sealing surface to reduce the erosion of the seal by the airflow 6. The double-acting throttling stop valve also has a multi-stage throttling function, with a large throttling pressure difference, which can be used for throttling and cut-off under high pressure 7. The packing adopts a V-shaped packing structure with self-sealing ability, which does not require adjustment and is extremely easy to open and close. An auxiliary sealing grease injection structure is provided at the stuffing box to make the valve packing sealing performance reliable 8. This valve can be repaired online, and the pipeline can replace a series of vulnerable parts such as packing under pressure 9. This valve is equipped with a large drain hole at the bottom of the valve. If necessary, it should be opened to clean the dirt in the valve |
| Applications Widely used as closed-circuit devices on pipelines of petroleum, natural gas, coal gas, liquefied petroleum gas, oil refining, airports, chemical industry, oil and gas storage and transportation, etc. |
