HAM-LET Pressure Regulators
HAM-LET Clean Gas Regulator
Single Stage Regulators
High pressure gases enter through the inlet of the regulator to the high-pressure chamber. When the hand wheel is turned clockwise, it compresses the spring and creates a force on the diaphragm, which pushes the regulator’s poppet open. This releases the gas into the low-pressure chamber, exerting an opposing force on the diaphragm which then closes the passage.
Equilibrium is reached, when the spring force on the diaphragm is equal to the opposing force of the gas in the low-pressure chamber. In a single-stage regulator, delivery pressure increases as cylinder pressure falls, because there is less gas pressure exerted on the diaphragm. Thus, frequent adjustment of the
control knob is required to maintain a constant delivery pressure. Therefore, a twostage regulator is recommended for applications requiring constant outlet pressure.
A dual-stage regulator functions like two single-stage regulators connected in line. The first stage reduces the inlet pressure to a preset intermediate pressure.
By adjusting the control knob the second stage reduces the intermediate pressure to the desired delivery pressure. Like the single-stage regulator, outlet pressure from the first stage of the two-stage regulator rises as cylinder pressure decreases.
However, the second-stage of the dual-stage regulator regulates, according to the preset level entered with the control knob, the point of use pressure as desired.
Thus, delivery pressure remains constant even as the cylinder pressure lowers, eliminating the need for frequent control knob adjustment needed for a single-stage regulator.
One of the most commonly asked question we hear from potential customers is:-
“Are your tube fittings Interchangeable and intermixable with Swagelok, Hoke Gyrolok, Parker A-lok etc”.
We are so confident that our components are manufactured to the same exacting standards and tolerances that we also provide a limited lifetime warranty to eradicate the misleading claims that components cannot be intermixed.
For additional information, test reports and actual “hands on demonstrations” please contact us to find out more.
As a result of extensive testing and evaluations by HAM-LET and from the many thousands of satisfied customers around the world who have chosen our products for SAFETY, RELIABILITY and PERFORMANCE, HAM-LET hereby warrants all products to be free from defects in material and workmanship.
This warranty shall also extend to the intermixing of components manufactured by several American organisations such as Swagelok, Hoke, Parker and HAM-LET products.
The manufacture shall be liable only if the product is used as specified in the current catalogues and written instructions.
The purchaser’s remedies shall be limited to replacement and installation of any parts that fail through a defect in material or workmanship. Manufacture specifically disavows any other representation, expressed or implied, warranty, or liability relating to the condition or use of the product.
