Ammonia Valves & Assemblies
Safety Relief Valves
- They relieve pressures, liquid or vapor, that exceed the design pressure of a tank or piping system.
- They have a finite life span due to the rubber seat; expiration noted on valve.
- They are fitted with plastic caps to prevent contamination and as an indication that a valve has opened.
- They are mounted on a three-way valve manifold allowing one valve to be open and the other isolated.
Hydrostats
- They are installed on a piping system wherever liquid can get trapped in the line to release the liquid and prevent a hydrostatic eruption.
- If a hydrostat leaks, a second hydrostat can be threaded into the first one making it unnecessary to drain the line for replacement.
Tank Filling Valves
- They are the valves the vapor and liquid hoses are connected to when filling a storage tank.
- They are fitted with protective caps to prevent contamination and to identify ammonia liquid and vapor connections. The liquid cap is orange and the vapor cap is yellow.
- Vapor Connection: Controls the delivery pressure differentials by transferring vapor from one tank to another.
- Liquid Connection: Controls liquid withdrawal.
- A vent valve should be installed between the fill valve and the protective cap to relieve pressure before protective cap is removed.
Vent Valves
- They are installed to relieve pressure before a valve is opened.
Excess Flow Valves
- They are connected to all piping and hose connections to prevent a massive release in the event of a catastrophic line break; NH3 only.
Pressure Gauges
- They measure the pressure inside a tank, usually a range of 0 - 400 psi.
85% Outage Gauge
- They indicate when a tank reaches the 85% liquid level. Trace vapors are released when liquid level is below 85%; A puff of white smoke is released when liquid level is at or above 85%.
Liquid Level Gauge
- Liquid level gauge reads the percent (%) of total tank capacity. Capacity of tank (gallons) times the percent reading equals gallons.
Rotogauges
- They measure the liquid level of a tank. You take the average of clockwise and counterclockwise readings.
- When the dip tube reaches below the liquid level a puff of white smoke appears.
Pressure Transmitter
- It transmits the pressure readings to the PLC to display on the screen for operators.
Level Transmitter
- It transmits the level readings to the PLC to display on screen for operators.
Temperature Transmitter
- It transmits the temperature readings to the PLC to display on screen for operators.
