There are several types of pressure regulating valves available, each designed for specific applications and operating conditions. Some common types include pilot-operated valves, diaphragm-operated valves, and direct-acting valves. Pilot-operated valves use a separate control line to adjust the pressure, while diaphragm-operated valves use a flexible membrane to control the opening of the valve. Direct-acting valves, on the other hand, operate without the need for external control lines or mechanisms.
