Sluice Rubber Gate Seals P/J Type Gate Rubber Seals
Rubber Gate seal, also known as p-type rubber water-stop, gate seal is an important part of the hydro-power project gate, the gate is to ensure airtight seal water, the key components of normal operation.There are different types with or without PTFE cladding for increasing in sliding friction that P Type, L Type, W Type, Ω Type, V Type, U Type, Customized Type etc. While every type also can be divided into several groups. 
Classification of rubber gate seals
Common type seal
Rubber seal is made of natural rubber (synthetic rubber) by mixing device (open-roll or mixer) segmented mastication, mixed with special antioxidant, vulcanization accelerator, vulcanization aid, reinforcing agents, after a plasticizer and a dozen other raw materials obtained semi-finished rubber compound, then placed in a certain cavity mold by vulcanizing press at high temperature and pressure conditions in the system in line with the integrated hydraulic steel gate sealing requirements sealing elements.
Rubber composite type seal
The low friction, high wear resistance of PTFE film composite to seal Face seal is called a composite rubber seal, PTFE film for uninterrupted work surface is not segmented overall, enhancing Face and seal section .
High-strength nylon canvas seal
The high-strength nylon canvas placed rubber seal for enhanced, low friction, wear resistance of the seal doubling folder.
High-strength nylon canvas rubber composite seal
Both plus high-strength nylon canvas again and again PTFE film of water seal folder.
Its materials can be Neoprene, SBR, Natural Rubber etc.
Special drawings rubber products from clients are acceptable in producing.
