Safety valves come in three types: balance, conventional, and pilot operational. What are the corresponding Chinese terms for these?

What types of safety valves do the three categories of balance, conventional, and pilot operational correspond to respectively? How should they be translated?
I can’t remember the exact structure of the backpressure-balancing safety valve; API 520 provides a detailed description of it. It seems to be a mechanism that ensures equal pressure on both sides of the valve’s sealing element, thereby eliminating the influence of backpressure at the discharge port. Traditional (conventional) safety valves and pilot-operated safety valves – the latter use a smaller valve to control the opening and closing of a larger valve – are suitable for applications requiring large diameters, high flow rates, rapid operation, and high sealing standards. I’m not sure if this counts as being faithful, expressive, and elegant: lol
balance: backpressure balanced safety valve; conventional: ordinary safety valve (i.e., the most common spring-loaded safety valve); pilot operational: pilot-operated safety valve
The answers for floors 2 and 3 are basically correct. As a supplement regarding \"balance,\" its full name is balanced spring safety valve – it is a safety valve that operates based on the action of a spring, with the set pressure controlled by this spring. Pistons or bellows are used to reduce the impact of back pressure on the operating performance of the safety valve.
Safety valves are of three types: balance, conventional, and pilot operational. What are the corresponding Chinese terms for these? Balance: balance valve, pressure equalizing valve; Conventional: ordinary safety valve (spring-type); Pilot operational: pilot valve. For reference only
