The ZCGYA Carbon Steel Hydraulic Safety Valve is an indispensable secondary safety protection device for storage tanks. Designed to function as a fail-safe, this valve utilizes a liquid seal principle—typically employing oil—to rapidly release overpressure or admit vacuum in the event that the primary breather valve fails to operate.
Producdt Description：
The ZCGYA Carbon Steel Hydraulic Safety Valve is an indispensable secondary safety protection device for storage tanks. Designed to function as a fail-safe, this valve utilizes a liquid seal principle—typically employing oil—to rapidly release overpressure or admit vacuum in the event that the primary breather valve fails to operate. Constructed from high-strength carbon steel, the ZCGYA is specifically engineered to prevent catastrophic tank deformation or explosions.
Operating pressure:
Note:
Under normal circumstances, (fire) breathing valve operating pressure to B shall prevail;
Applicable materials: gasoline, kerosene, diesel, aromatics, sulfur, air and other petrochemical materials;
Environment temperature: -40 °C -+60 °C;
Shell material: HT, AL, A3, 18-8, 304, 304L, 316, 316L.
Flange standards: HG20592-97 PN1.0 (also can be produced according to user specified criteria)

Q1: What is the primary role of the ZCGYA Hydraulic Safety Valve? A1: It serves as an emergency secondary safety device. Its main role is to protect the storage tank from overpressure or vacuum damage in scenarios where the primary breather valve fails.
Q2: Why choose Carbon Steel for the valve body?
A2: Carbon steel offers excellent mechanical strength and durability at a competitive cost, making it the preferred choice for large-scale industrial storage tank applications where high-pressure integrity is required.
Q3: How does the “Hydraulic” aspect work in this safety valve?
A3: The valve uses a sealing liquid (typically a specialized oil) to create a barrier. The height of this liquid column determines the pressure and vacuum settings at which the valve will open to release gas or admit air.
Q4: What maintenance is required for the ZCGYA series?
A4: The primary maintenance involves regularly checking and replenishing the sealing liquid to ensure the level remains at the designated height for accurate pressure control.
Q5: Can the ZCGYA valve be customized for different flange standards?
A5: Yes, we can manufacture the connection flange to meet various international standards, including ANSI, DIN, JIS, or local GB standards, ensuring a seamless fit for your existing pipeline system.
