Knife gate valve with one-piece centering housing for clamping between flanges according to EN 1092-1 type 11 form B - PN10. For flanges according to ANSI 150 on request. With this slide, the pressure is applied from one side, sealing on one side). Side parts made of epoxy-coated steel enable easy assembly of electro / mechanical or inductive limit switches. The operation to open and close the material slide is done by means of a hand wheel.
Other drive types can be ordered in our shop, for example:
- Hand lever
- pneumatic drive (double or single acting)
- electric drive
- hydraulic drive
Flow media
Liquids and contaminated media with fiber content, viscous media, waste water, sewage sludge, food, etc. (plastic granulates, powder, sand or similar materials on request). Not suitable for steam.
Housing
GG-25, primed and polyester coated (baked 190 °, 20min) or stainless steel 1.4408. Overall length according to EN 558-1 row 20.
Seat seal
Depending on the version, metal or soft sealing with NBR, EPDM, FKM, silicone or PTFE seal
Stuffing box packing
3-piece seal set, standard:
1x synthetic fiber, PTFE-coated, PTFE / oil filling
1x edge-reinforced (Kevlar®) seal
1x NBR, EPDM or FKM ring (bulk goods on request)
Other pack designs are available, for example:
- X ring
- Edge reinforced seal
- Copper seal
- Stainless steel seal
Polished blade (knife)
Material: stainless steel 1.4307 or 1.4404
Other knife designs are available, for example:
- hardened
- polished
- MPF-coated: non-stick and highly resistant to acids and chemicals
Spindle
Double-bearing, non-rising spindle with trapezoidal thread. The slide blade is only guided against or against the seal at the end of the closing process, so there is no dragging during the adjustment process and therefore a lower torque.
Material: stainless steel 1.4305 or 1.4404.
Leak rate
Please note that a leak rate of 0.4% of the Kv value is to be expected with metal-to-metal-sealing gate valves (low-viscosity media).
Further variants of the EBWGE knife gate valve can be ordered online in our shop:
- Knife gate valve in nominal widths from DN50 to DN400, larger nominal widths on request
- Knife gate valve for pressurization on both sides (bidirectional)
- Knife gate valve with ATEX approval for use in explosive atmospheres.
The nuts of the stuffing box must be adjusted after assembly. Please note the installation and operating instructions for commissioning and our technical data sheets for further information and operating conditions!
