2510B Top-guide single-seat bellow sealed regulating valve
2510B Top-guide single-sear bellow sealed regulating valve consists of pneumatic film actuators and bellows seal single seat valve. The components of its valve core use bellows seal structure, the upper valve cover still have packing seal and that become double sealing which can strictly prevent medium from leak. For this reason, this kind of valve is applied to adjust highly toxic, expensive, volatile or easy penetration of technological media.
