sluice gate valve

This Large Size Sluice Gate Valve has the following characteristics:　 1. Simple installation, solid structure, space saving; simple operation and maintenance, reduce operating costs，Strong corrosion resistance. 2.The body and frame are made of cast iron, and the water stop surface is inlaid with copper alloy or stainless steel and other corrosion-resistant materials with strong corrosion resistance, which is especially suitable for sewage or sea water environment. 3.Where there are special requirements, nickel chromium alloy cast iron and other materials with stronger corrosion resistance can be used. 4.The sealing of Electric penstock valve is processed as a whole, with good sealing effect and long service life of metal sealing.

1.The channel Sluice Gate is controlled by a mechanically operated spindle. 2.The sluice gate valve drawing can be operated automatically through the use of an actuator. This could be activated once specific set levels are reached. Therefore, removing the need for any human interaction. 3.The manual Penstock Gate also seal a pipe on all 4 sides, this is something that stoplogs are unable to do.

1.The sluice gate valve is controlled by a mechanically operated spindle. 2.The Water Penstock valve can be operated automatically through the use of an actuator. This could be activated once specific set levels are reached. Therefore, removing the need for any human interaction. 3.The Wall type penstock valve also seal a pipe on all 4 sides, this is something that stoplogs are unable to do.

1.Usage of penstock Usage: penstocks are wildly used for water supply and sewage treatment projects to cut off the media . The normal media is raw water, clean water and sewage etc. 2.Different structure penstocks Channel penstocks have fixed parts for channel by concrete pouring. Wall type penstocks use anchor bolts to fix the penstock to the hole surface.

1.Corrosion resistance: acid and alkali resistance and most of the corrosive chemicals and sewage, seawater; 2. Good sealing performance: the rubber is used to seal metal, and the water stop rubber ring is hollow structure with good sealing performance; 3. Small torque: for the light weight of the door plate, the friction resistance between the door plate and the guide rail is small, so the operating torque of the hand wheel is not greater than 100N； 4. Independent structure: reliable temperature and rigidity welding structure, high-performance seals ensure the effective opening and closing of the gate, independent seal and wedge design make the gate more reliable, and can be subject to large reverse water level; 5. Long service life: because the door plate and the guide rail only contact with the last small section of sealing, the sealing wear is very small; The service life of stainless steel gate is more than 10 years, and that of carbon steel gate is more than 5 years; 6. Convenient maintenance: the wedge block can be adjusted.

1.The penstock gate can be made according to user's requirements 2. Corrosion resistance: acid and alkali resistance and most of the corrosive chemicals and sewage, sea water, etc. 3. Good sealing performance: soft rubber seal is adopted, and the water stop rubber ring is hollow structure, with good sealing effect

1.The sluice gate valve for water is controlled by a mechanically operated spindle. 2.The square penstocks valve can be operated automatically through the use of an actuator. This could be activated once specific set levels are reached. Therefore, removing the need for any human interaction. 3.The welding penstock valve valve also seal a pipe on all 4 sides, this is something that stoplogs are unable to do.

1.This sluice gate valve is a type of valve for controlling water or sewerage. 2.This Channel type penstock is, in essence, a sliding door which can be operated by hand or an actuator （AUMA&Rotork&Festo） 3.This big size sluice gate valve raises to open and allow the passage of water and lowers to isolate the flow. 4.The whole rising stem on this WCB sluice gate valve can stand wear and tear, and every rising stem we also provide the Stem protection sleeve.

Non-rising stem knife gate valve have a stem nut on the disc,when turn the stem by hand,the disc will go up and down with the stem nut,this design used where the installation space is limited. We have some large diameter knife sluice gate valve body in stocked,so we can provide short lead time for our customers. All the flange knife gate valve will tested one by one before shipping,test according to API598 GB/T13927 ext. Body test 1.5*PN,seal test 1.1*PN, if the knife gate valve is bi-directional, then we will test two side of seal.
