Knife Gate Valve Manufacturer in India | Fluidtecq
Knife Gate Valve Manufacturer in India — Engineered for Slurry, Ash, Dust and Abrasive Medi
Fluidtecq designs and manufactures knife gate valves for process industries where standard valves fail under abrasive, high-solids, or clogging media. Since 1989, Fluidtecq has supplied manual and automated knife gate valves for isolation and discharge duty across power, cement, mining, pulp and paper, and wastewater treatment applications — engineered around the actual media and operating condition, not a generic catalogue spec.
Product Preview:
A knife gate valve uses a flat gate that travels perpendicular to the flow path, physically cutting through settled, fibrous, or particle-laden media rather than sealing around it. This makes it the standard valve choice for slurry, sludge, ash, dust, and other difficult media where ball, globe, or standard gate valves are prone to jamming, clogging, or premature seat wear. Fluidtecq's knife gate valve range is manufactured for manual operation as standard, with pneumatic and electric actuation available as part of a complete automated valve package.
Available Configurations
Manual (handwheel or hand-lever) operation
Pneumatic actuated — single-acting (spring-return, fail-safe) or double-acting
Electric actuated, for sites without instrument air availability
DN 50 to DN 2400 — nominal bore range manufactured
Wafer, Slug and Flanged end connections
Pressure from 3.5 to 10 Bar across the standard series
Technical Specification
Materials of Constructio
Fluidtecq offers knife gate valves in material combinations selected to match media abrasiveness, corrosiveness, and operating temperature. Body materials including Cast Iron (CI), Carbon Steel (WCB), Stainless Steel (SS304, SS316, SS316L, CF8, CF8M), and specialty alloys such as CK20, Hastelloy C276, and Monel; gate materials in SS304, SS316, SS316L, Duplex Stainless Steel, and Hastelloy; and seat materials including EPDM, NBR, Viton (FKM), Metal-to-Metal, and other application-specific resilient or high-temperature sealing materials are finalised for each application based on the actual process duty rather than a single standard specification.
Actuation Options
Manual — handwheel or hand lever operation for infrequent isolation duty.
Pneumatic — single-acting (fail-open/fail-close) or double-acting actuators for remote or automated operation.
Electric — for locations without a reliable instrument air supply
Chain Wheel — for elevated or inaccessible installations requiring safe manual operation from floor level.
See our Valve Automation page for how these actuation options integrate into a complete automated package.
Automation Accessories
Knife gate valves can be supplied as part of a
complete automated package, including:
Solenoid valves
Limit switch boxes for position indication
Air filter regulators
Positioners, for modulating or intermediate-position duty
Junction boxes and control panels for remote/PLC operation

Frequently Asked Questions
What is a knife gate valve used for?
Knife gate valves are used to isolate or control the flow of slurry, sludge, ash, dust, pulp, and other abrasive or solids-laden media where conventional valves are prone to clogging, erosion, or excessive wear.
Can Fluidtecq automate a knife gate valve?
Yes. Fluidtecq supplies knife gate valves with pneumatic (single-acting or double-acting) and electric actuators, complete with solenoid valves, air filter regulators (AFR), limit switch boxes, positioners, junction boxes, and control panels as a fully integrated automation package.
Does Fluidtecq export knife gate valves outside India?
Yes. Fluidtecq supplies knife gate valves to customers across India as well as international export markets, providing application engineering support and customised valve automation solutions for industrial process applications.
What industries commonly use Fluidtecq knife gate valves?
Fluidtecq knife gate valves are widely used in power generation, cement, steel, mining & mineral processing, pulp & paper, sugar, wastewater & effluent treatment, chemical & fertiliser plants, foundries, dust collection systems, and biomass plants.
Is a knife gate valve suitable for high-pressure service?
Knife gate valves are primarily designed for low- to medium-pressure isolation service in slurry, bulk solids, ash handling, and process applications. The appropriate pressure rating should be selected based on the specific application and operating conditions.
