The T-H3-DV-P is well suited for residential/ commercial applications such as small restaurants and beauty salons. Complies with Ultra-Low NOx regulations. Utilizing HRS35 copper alloy for the heat exchanger tubing, the T-H3 is also suitable for heavier residential usages such as space heating or domestic recirculation systems. Remote control included as a standard feature. The range varies from wafer type lift & swing type non-return valve. Casting Non Return Valves are field suited and available in a range of 15 NB to 100 NB. Flanged and screwed. The Non Return Valves are designed to ensure full flow, efficient function, and minimum pressure drop across the valve.

Process Flow Diagram Symbols - Equipment

Pumps and tanks come in a variety of designs and shapes.

Compressor is a mechanical device that takes in a medium and compresses it to a smaller volume. A mechanical or electrical drive is typically connected to a pump that is used to compress the medium.

Pump refers to a mechanical apparatus using suction or pressure to raise or move liquids, compress gases, or force air into inflatable objects such as tires. The symbols for pumps may closely resemble those for compressors.

Mixing is a gear that combine some materials or put them together to form one substance or mass.

Mixing vessel is a container that is used to blend several components together.

Heat exchanger is an equipment used to transfer heat energy between two process flows. Heat exchangers transfer heat energy through conductive and convective heat transfer.

Cooling towers transfer heat energy to the outside air through the principle of evaporation.

Cooler is a device, container or room that cools air through the evaporation of water or keeps cool.

Furnace means a tool for heating a continuous current of air by means of a fire contained within the apparatus and without mingling the fresh air with the products of combustion.

Boiler is a closed vessel in which water or other fluid is heated.

Tank is used to store process fluids of various types, under different process conditions.

Process Flow Diagram Symbols - Valves

Gate valve is a device used to control the flow of liquids and gases.

Check valve, also known as one-way valve, is to prevent the line of medium back.

Globe valve refers to a mechanism used to control or stop the flow of liquid or gas through a pipe.

Ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it.

Butterfly valve is installed between two flanges using a separate set of bolts for each flange.

Angle valve is oriented at a 90 deg angle of gate valve. Datacolor spyder x software.

Process Flow Diagram Symbols - Piping Lines

Process flow diagrams use special piping lines to represent how signals are transmitted between equipments. These symbols are used to identify how the instruments in the process connect to each other. And what type of signal is being used. (electrical, pneumatic, data, etc)

All lines are fine in relation to process piping lines.

Major pipeline is for connection of the equipment in any position.

Major Straight line is sued to connect the equipment in the same horizontal or Vertical position.

Process connection help to create the process flow between equipments. Double click process connection to edit description.

Process Flow Diagram Symbols - Instruments

Process Flow Diagram use symbols and circles to represent each instrument and how they are inter-connected in the process.

Users can easily change types of the instrumentation symbols by clicking the quick action button while designing.
