Knife-Gate Valves Series A supply at Malaysia (Environmech Sdn Bhd)-Selangor

Knife-Gate Valves Series A

- Unidirectional wafer-design knife gate valve.
- One-piece cast body with guides to support gate and seat wedges.
- Provides high flow wates with low pressure drop.
- Various seats and packing materials are available.
- Face-to-face dimension in accordance with CMO standard.
- An arrow is marked on the body indicating the flow direction.

General Application:
- This knife gate valve is suitable for liquids that contain a maximum of 5% suspended solids. If it is used for dry solids in gravity feed applications it should be installed with the arrow on the body pointing in the opposite direction to the flow. Designed for applications such as: 
- Paper Industry
- Chemical plants
- Sewage treatment
- Mining
- Pumping
- Silo emptying
- Food Industry

Size : ND50 to ND2000 (large sizes on request)

Working Pressure:-
- ND 50 to ND 150 : 10kg/cm2
- ND 200 : 8kg/cm2
- ND 250 to ND 300 : 6kg/cm2
- ND 350 to ND 400 : 5kg/cm2
- ND 450 to ND 600 : 3kg/cm2
- ND 700 to ND 1400 : 2kg/cm2

- These pressures must be applied to the valve in the direction of the arrow marked on the valve's body. Due to the valve's design with gate support guides, 30% of these pressures can be applied in the opposite direction to the arrow.

Standard Flanges: -
- DIN PN10 and ANSI B16.5 (class 150)

Other Common Flanges:-
- DIN PN6 : BS"D" and "E"
- DIn PN16 : ANSI 150
- DIN PN 25 : Others on request

Potential Explosive Atmospheres Directive : DIR 94/9/EC (ATEX) CAT.3 ZONE 2 and 22 GD

Quality Dossier :
- All valves are tested hydrostatically at CMO and material and test certificates can be provided.
- Body test = working pressure x 1.5
- Seat test = working pressure x 1.1
