A Pressure Regulator is a mechanical device which is designed to regulate system flow pressure in response to downstream or upstream pressure changes.
Regulators are available in various types, designs and is different materials of construction.
A pressure reducing regulator helps you to control the downstream pressure and a back pressure regulator helps you to control the upstream pressure.
Pressure reducing regulators controls outlet pressure by balancing an adjustable spring force against the forces caused by inlet and outlet pressures. The spring force is adjusted by turning the stem or handle, which sets the desired outlet pressure. As inlet pressure decreases, the force balance changes. To compensate, outlet pressure will increase.
Back pressure regulators control inlet pressure by balancing an adjustable spring force against the force of the inlet pressure. The spring force is adjusted by turning the stem/ handle, which sets the desired inlet pressure. When the force caused by the inlet pressure rises above the force of the spring, the regulator opens until the spring force and inlet pressure are balanced again.
