The flow characteristics of ZECO slab gate valve with diversion hole are the same as those of the pipeline of the same diameter. Compared with the other two kinds of valves, the flow characteristics of the adjustment type slab gate valve without diversion hole are better than those of the ordinary type without diversion hole. Therefore, in the long pipeline, natural gas, oil industry, slab gate valve with diversion hole is particularly widely used. ZECO Valve Group, as a well-known manufacturer of slab gate valves in China, can deliver large scale, excellent quality and exquisite appearance slab gate valves in full accordance with API 6D standard.
1. ZECO slab gate valve is equipped with grease injection hole, in case of sealing surface damage, the maintenance personnel can easily inject sealant through the grease injection hole to maintain the sealing surface to ensure the normal switching performance of the valve or in the case of maintenance, provide injection sealant to lubricate the sealing surface to extend the normal service life of the valve;
2. When ZECO slab gate valve is fully open, the channel is the straight pipeline, the flow resistance coefficient and pressure loss are very small and almost negligible, which can reduce the cost of pipeline operation for users, and the pills can be used for cleaning when cleaning the pipeline;
3. ZECO slab gate valve is equipped with automatic pressure relief protection device, which can automatically relieve pressure in the case of over pressure in the middle chamber of the valve body to protect the safe use of the valve;
4. The floating seat structure of ZECO slab gate valve ensures that the valve can be sealed in both directions.
