Material selection for electric gate valve DN200: The valve body and packing culvert are both precision cast, and materials such as 304, 316, 316L, WCB, and 2Crl3 can be selected according to user needs. The sealing ring is made of PTFE reinforced polytetrafluoroethylene material, which is corrosion-resistant, wear-resistant, and slag free.
Electric gate valve DN200It is a widely used valve equipment in the industrial field, mainly used to control the flow of media in pipelines.
I. Overview
Equipped with a multi turn electric device, the valve plate can move in a straight line up and down to achieve remote control of valve opening or closing. The valve body material is usually cast steel or stainless steel, with a diameter range of DN200, a service temperature of up to 425 ℃, and a nominal pressure of 1.0-1.6MPa.
2、 Product Features
Design Structure:
The bottom of the blade is processed into a blade shape, which has cutting function for soft materials such as fibers, pulp, and wood pulp, and also has good opening and closing function.
Material selection:
The valve body and packing culvert are both precision cast, and the material can be selected from 304, 316, 316L, WCB, 2Crl3 according to user needs.
The sealing ring is made of PTFE reinforced polytetrafluoroethylene material, which is corrosion-resistant, wear-resistant, and slag free.
Self centering design:
The valve plate has 5 support points, which provide good self centering of the valve plate. When the valve is in the closed state and subjected to back pressure, the valve plate does not shift.
Multiple driving modes:
Can be configured with handwheel, manual zipper, spur gear transmission, bevel gear transmission, pneumatic and electric.
通道形状:
Internally, it can be made into V-shaped, triangular, and pentagonal channels. The V-shaped gate can be used as a regulating control.
Connection form:
The connection forms include clamp type and flange ear type, and the seals include metal to metal hard seal, metal to polyurethane, and reinforced polytetrafluoroethylene soft seal.
3、 Applicable media and working conditions
Applicable media: gold ore powder, tailings, pulp, wood pulp, fiber, dust, chemical treatment wastewater, sedimentation tank, mineral sand, slag, coal slurry, asphalt, silo outlet, fruits, grains, cement slurry, slaughterhouse wastewater, etc.
4Electric gate valve DN200maintenance
Storage environment: It should be stored indoors in a dry and ventilated area, with both ends of the pathway blocked.
Regular inspection: Regularly remove dirt and apply rust proof oil.
Maintenance: Regularly check whether the sealing surface is worn, whether the trapezoidal thread of the valve stem and valve stem nut is worn, whether the packing is outdated or ineffective, and make necessary replacements.
