1. Sealing emergency grease injection rescue: due to the foreign matter in the medium or fire, the valve seat seal fails unexpectedly. The grease injection valve provides a quick connection with the grease injection gun. The imported pump can inject the sealing grease into the sealing part of the valve seat conveniently and quickly to alleviate the leakage.

2. Reliable valve stem seal and low operating torque: in addition to the standard sealing ring, O-ring is also set on the packing gland to ensure the reliability of the valve stem seal; the graphite packing and sealing grease injection are added to minimize the valve stem leakage after fire. The sliding bearing and thrust bearing of the valve stem make the valve easy to operate.

3. Full bore or reduced diameter: full bore or reduced diameter structure can be selected as required. The flow aperture of full bore valve is consistent with the inner diameter of pipeline, which is convenient for pipeline cleaning.http://www.didlink-valve.com/

4. Valve stem can be lengthened: according to the needs of installation or operation, the valve stem can be lengthened. Extended rod ball valve, especially suitable for city gas and other occasions where buried pipeline is needed. The size of lengthened valve stem is determined according to customer's requirements.

5. Flexible operation: the valve seat and stem bearing with small friction coefficient and good self-lubricating property can greatly reduce the operating torque of the valve. Therefore, the valve can be operated flexibly for a long time even without sealing grease
