Basic Info
Model No.: SC
Product Description
Model NO.: SC Material: Cast Iron Pressure: Ordinary Temperature Seal Surface: Wedge Gate Valve Usage: Safety Application: Industrial Usage, Water Industrial Usage Specification: DN50-2000 HS Code: 8481804090 Type: Straight-through Connection Form: Casting Actuator: Manual Thread Position of Valve Rod: Outside Gate Valve Standard: DIN Trademark: sc Origin: China
Quick Details
Standard or Nonstandard: Standard
Structure: Gate
Pressure: Medium Pressure
Power: Manual
Material: Casting
Temperature of Media: Medium Temperature
This valve, whose shield is attached to body to keep away the gate's corruption from outside condition, can be used in outside hard conditions thus increasing the life of the gate. The sealing principle is that when the gate is closed to the end, oblique plane of gate valve encounters wedge block of gate to close to achieve sealing effect, which makes the valve less blockage media. Its structure can be made into a hard seal, soft seal. Sealing requirements base on customer's selection. Soft-seal is a metal pressure sleeve to rubber ring sealed envelope locked in the valve seat tank, making ring will not fall off, and it's convenientto take off metal pressure sleeve to replace the seat seal, besides ,not onlyimprove the valve's service life, butalso saves the user'scost . The advantage of gatevalves are: open and close flexibly ,light instructure, excellence insealing, and the soft seal rubber seal can be very easy to replace and so on, not only increases valve's life, but also saves a waste of resources.
