Gauge Savers:

Features:

~ Compact Design

~ Automatic Positive Action

~ IN-Line Installation

~ Repeatable performance

~ Prevents Damage To Gauge Due To Sudden Surge

Technical Features: Our Gauge Saver is also sometimes called as Over Load Protector . It cuts off pressure rises above the desired pressure value (pre-set value) thus preventing failure of pressure gauge and stops possible damages such as hazardous leakages, explosions etc.

The Gauge Saver shuts off the system with quick and positive action of built in push-rod device. As and when, the pressure falls below the pre-set pressure value, the line and/or the pressure gauge is automatically put in to operation again. The Gauge Saver is of extreme importance and necessity for the protection of the pressure sensitive instruments against over pressures, sudden line induced pressure surges which are principal causes of the instrument and subsequent system failure. The Gauge Saver can be supplied to function at different cut-off pressure values on special request.

The repeat accuracy of the unit depends on the rate of pressure rise. However, an accuracy of ± 10% of the set pressure may be expected.

Typical Applications: These gauges are used in Corrosive Medium & Chemical Environments, Food Industries.

Pulsation Dampeners:

Features:

~ Compact Design

~ Automatic Positive Action

~ IN-Line Installation

~ Repeatable performance

~ Prevents Damage To Gauge Due To Sudden Surge

Technical Features: Universal Pulsation Dampener should be used when pressure gauge is subjected to rapid pressure fluctuations which make the pointer vibrate and difficult to read. It is unique combination of Ball Check Cut Off and a Fine Thread Chock Valve.

After installation of the dampener, the fine thread chock valve should be adjusted to reduce pulsation in the line and pointer vibration. Dampener can also be used as Shut Off Valve by adjusting thread chock valve to maximum to achieve absolute isolation of the gauge from line. For cleaning the dampener, remove the ball check screw from the base by means of an Allen key , and fine thread screw and locknut from the side. Metal parts should be cleaned in commercial solvent.

Typical Applications: In pulsating line pressure, to protect gauge from sudden surge pressure.

Pressure Snubbers:

Features:

~ Compact Design

~ Automatic Positive Action

~ IN-Line Installation

~ Repeatable performance

~ Prevents Damage To Gauge Due To Sudden Surge

Technical Features: To save the instruments from getting damaged due to severe line pulsations and pressure surges, to protect the accuracy and to increase the life of the instrument, it is necessary to install these protective devices along with the instruments.

Each snubber is supplied with pistons of three different diameters. Depending on viscosity of the fluid and amount of dampening desired, piston size should be selected. Each piston is marked with numbers 1,2 and 3. Piston 1 should be used with fluid having less viscosity or where higher dampening is required. Piston 3 should be used where fluid viscosity is more or where less dampening is preferred.

Piston 2 is installed when snubber is supplied from the factory. Pistons are easily interchangeable. The snubber is completely self cleaning, as the piston moves up and down with the line pulsations it automatically forces out any sediments that might clog instrument.

Snubbers can be used for pressure, Vacuum or compound gauges and material should be selected depending on application.

Typical Applications: In pulsating line pressure, to protect gauge from sudden surge pressure.

Siphons:

Features:

~ Compact Design

~ Automatic Positive Action

~ IN-Line Installation

~ Repeatable performance

~ Prevents Damage To Gauge Due To Sudden Surge

Technical Features: Pressure gauge siphons are used to protect the pressure gauge from the effect of hot pressure media such as steam and also to reduce the effect of rapid pressure surges. The pressure medium forms a condensate and is collected inside the coil or pigtail portion of the siphon. The conden­sate prevents the hot media from coming in direct contact with the pressure instrument.

Typical Applications: In hot pressure media, to protect gauge from sudden surge pressure.

Thermowells:

Technical Features: Thermowells are used to protect the temperature sensors from industrial processes. These are made to suit applications with fabricated or bar stock design having end connection as thread or flange. The construction may be straight, tapered or stepped.

Typical Applications: To protect gauge from direct contact with medium

Needle Valves:

Typical Applications: Needle Valves allow precise regulation of flow They are mainly used in flow metering applications, especially when a constant, calibrated, flow rate must be maintained.
