Three way Y shape design provides dual pressure relief device system which is installed on one position, one is active for overpressure protection, the other is kept in reserve as a standby.
The operation of crossover is safe, handy and fast, it costs no more than one minute.
The quick crossover device protects workers from being exposed in dangerous environment.
Process shutdown is not needed when crossover, so high cost due to unscheduled shutdown can be saved.
The red handle indicates which side is active remarkably,
A vent valve is provided under each safety valve (and rupture disc), to relieve fluid out of the pipe before the isolated safety valve which is to be dismantled.
Balance valve of the quick crossover device provides low actuation torque, so crossover is very handy.
Meets temperature applications from cryogenic to +260.
Floating seat is helpful to keep sealed, even after switching many times.
Provides less than 3% pressure drop to the active save inlet, in accordance with API RP 520 part II.
We, Beijing Zhonghanghua Safety Valve Sales Co., Ltd established in 1998 which is the sales entity especially for safety valves and specialty valve designed and manufacutred by Beijijng Aerospace Propulsion Institute Pressure Relief Branch. Based on the company's philosophy of 'People oriented' and forcusing on providing best-in-class service and products to customers, the company already developed as one of the most important supplier for safety valves and specialty valves. By our continuing development, our products not only has been widely used in the most of domestic industry projects but also have been accepted and intalled to the industry projects by customers from USA, Germany, Canada and so on with excellent performace.
Our parent company Beijing Aerospace Propulsion Institute (CASC) was founded by 1958, which was the first research unit in China and involved in liquid propellant rocket engine development. Since 1984, CASC started to apply aerospace techniques to the industrial products development. The products have been successful developed such as thermal engineering equipments, special pumps, special valves, petrochemical equipments, measurement and control systems, environment protection systems for petrochemical and environment protecion industries. Most of them filled the domestic gap and enter the international market successfully.
