Valves and Instrumentations
Precision-engineered flow control and measurement components for seamless industrial operations.
Reliable flow control and precise measurement are the backbone of any solvent extraction plant and edible oil refinery. Our comprehensive range of valves, flanges, and high-precision instruments ensures that your plant operates with maximum safety, zero leakage, and optimum energy efficiency.
Ball Valves
Ball valves are essential flow control devices used in solvent extraction plants and edible oil refineries to start, stop, and regulate the flow of liquids and gases. They are especially important in handling solvents (like hexane), crude oil, and other process fluids, where tight sealing and safety are critical.
A ball valve consists of a spherical ball with a hole (bore) in the center. When the valve handle is turned, the ball rotates to either allow flow (open position) or block it completely (closed position). This simple mechanism ensures quick operation and reliable shut-off.
Key Features
Tight sealing (leak-proof)
Prevents solvent leakage, ensuring safety
Quick operation
90-degree turn for full open or close
Low pressure drop
Smooth flow through the valve
Corrosion resistance
Often made of stainless steel or special alloys
Durability
Long service life with minimal maintenance
Energy Miser Ball Valve
An Energy Miser Ball Valve is a specially designed ball valve used in solvent extraction plants and edible oil refineries to reduce energy loss and improve overall system efficiency. These valves are optimized for minimum pressure drop, tight sealing, and thermal efficiency, making them ideal for handling steam, condensate, solvents, and oil.
Unlike standard valves, energy miser ball valves are engineered to ensure smooth flow with minimal resistance, which helps reduce the load on pumps and compressors. In steam and heating systems, they may also feature insulated or heat-retaining designs, preventing unnecessary heat loss and improving energy utilization.

MS/SS Flange and Fitting
MS (Mild Steel) and SS (Stainless Steel) flanges and fittings are essential components used in solvent extraction plants and edible oil refineries for connecting pipelines, controlling flow direction, and ensuring leak-proof fluid transfer. They form the backbone of the plant’s piping system, handling materials like solvents (hexane), crude oil, steam, and water.
radio_button_checked Flanges:
Flanges are used to join pipes, valves, and equipment, allowing easy assembly and maintenance. They are available in various types such as:
- • Weld Neck Flanges – Strong and suitable for high-pressure applications
- • Slip-On Flanges – Easy to install and cost-effective
- • Blind Flanges – Used to close pipe ends
- • Socket Weld Flanges – Ideal for small diameter pipes
conversion_path Fittings:
Fittings help in changing direction, branching, or reducing pipe size. Common types include:
- • Elbows (90° / 45°) – Change flow direction
- • Tees – Divide or combine flow
- • Reducers – Connect different pipe sizes
- • Couplings and Unions – Join pipes securely
MS vs SS:
MS (Mild Steel):
Used in general service lines like water and non-corrosive fluids. It is strong, cost-effective, but requires coating to prevent rust.
SS (Stainless Steel):
Used in corrosive and critical areas, especially where solvents and edible oils are handled. It offers excellent corrosion resistance, hygiene, and durability.
Key Features
High strength & pressure resistance
Leak-proof and secure connections
Corrosion resistance
(Especially SS)
Easy installation and maintenance
VISI FLO
A Visi-Flo (also known as a sight flow indicator) is a simple yet highly useful device used in solvent extraction plants and edible oil refineries to visually monitor the flow of liquids inside pipelines.
It typically consists of a transparent glass tube or window housed within a metal body (MS or SS), allowing operators to directly see whether fluid—such as solvent (hexane), oil, or water—is flowing properly through the line.
Key Features
Visual flow confirmation
Without opening the pipeline
Transparent viewing section
For real-time monitoring
Leak-proof and pressure-resistant
Robust design
Available in MS and SS construction
For different applications
Can be fitted with rotor/indicator
For better visibility of flow
Types
Plain Sight Flow Indicator

Flow Meter
A Flow Meter is a critical instrument used in solvent extraction plants and edible oil refineries to measure the flow rate and quantity of liquids or gases moving through pipelines. It ensures accurate monitoring and control of fluids such as hexane solvent, crude oil, refined oil, water, and steam.
Flow meters help operators maintain process consistency, optimize efficiency, and reduce losses, which is especially important in systems dealing with flammable and high-value materials.
Key Functions
Measures flow rate
(LPM, m³/hr, etc.)
Tracks total volume/consumption
Helps in process control
And automation
Ensures accurate dosing
And transfer
Pressure Gauge
A Pressure Gauge (often written as pressure gage) is an essential instrument used in solvent extraction plants and edible oil refineries to measure and monitor the pressure of liquids and gases within pipelines and equipment.
It helps operators ensure that systems handling hexane solvent, oil, steam, and water are running within safe pressure limits, preventing equipment damage and hazardous situations.
settings Working Principle:
Most commonly, pressure gauges operate on the Bourdon Tube principle, where a curved metal tube expands when pressure is applied. This movement is mechanically linked to a needle that displays the pressure on a calibrated dial.
Key Features

Dry or glycerin-filled types
For vibration resistance
Constructed in MS or SS
For durability and corrosion resistance
Can handle high pressure
And temperature conditions
Vaccum Gauge
A Vacuum Gauge is an important instrument used in solvent extraction plants and edible oil refineries to measure pressure below atmospheric level (vacuum conditions). It helps monitor and control processes where air or gases are removed, ensuring efficient and safe plant operation.
settings Working Principle:
Most vacuum gauges work on the Bourdon Tube principle, where a specially designed tube reacts to negative pressure (vacuum) and moves a needle on the dial to indicate the vacuum level.
