Valve structure are two major categories: spring and leveraged. Spring means sealing valve and valve seat by spring force. Leveraged rely on leverage and weight force. With the large capacity needs, but also a pulsed valve, also known as pilot safety valve from the main valve and auxiliary valve. Valve Co., Ltd. specializes in producing Shandong Everbright safety valve safety valve manufacturer, welcome new and old customers to order our products! Opening pressure adjustment: ① before valve factory, should be adjusted by one of its opening pressure to the setting value of user requirements. If the user make spring working pressure level A27H spring inching valve price, press in general should adjust the pressure level of the lower limit of the factory. ② users before the safety valve is installed on the protected equipment or before the installation, you must re-adjusted at the installation site, in order to ensure the safety valve set pressure value to meet the requirements. Such non-direct acting valve safety valve can be divided into pilot safety valve, safety valve driving force auxiliary device. Pilot valve is to rely on the media discharged from the pilot valve to drive or control. The pilot valve itself is a direct-acting valve A27H inching valve springs offer, sometimes with other forms of valves. Pilot valve suitable for high pressure, large diameter occasions. The main valve pilot valve can also be designed to rely on the work of the media to form a sealed valve manufacturer in Weifang, or can be applied direct acting valve is much larger than the mechanical load on the valve, which has a good sealing performance. At the same time, it moves very little affected by backpressure. The disadvantage is that it is reliable safety valve with the main valve and pilot valve related action as a direct-acting valve as quickly, reliably, and more complex structure.
