The shuttle valve is a straight stroke valve, which is a valve in which the valve body and actuator are combined into one. Its advantages are small size and easy installation. Coupled with the particularity of the internal piston structure, the medium pressure has almost no resistance interference on the piston, thereby achieving fast switching and low pressure loss. Examples: ESG200 pneumatic shuttle valve, 201 pneumatic shuttle valve, 202 electronically controlled shuttle valve, 204 pneumatic flange shuttle valve, OMALVIP shuttle valve. The shuttle valve is an excellent design product in which the actuator and valve body are combined into one. Since the valve body, piston, and valve core are all made of stainless steel, they are more beautiful and high-end in appearance. In actual use, the seals have almost no contact with the medium and are more corrosion-resistant, so the practical scope is wider. In addition, the internal Only one component (piston) is moving, which makes the movement simple and reliable, has a long life, makes maintenance easier, and can be installed in any direction.
