The two versions of the flow limitations - main flow limitations and pilot flow limitation adjust and install the valve accordingly to the pressure and flow of the throttling. Pneumatic check valve with instant push-in fittings provides a durable sealing with most types of tubes and plugs. This throttle valve connector has a high-quality thermoplastic polymer housing that maximizes the resistance against heat and corrosion. One-touch push fitting offers easy installation along with quick hold and release mechanism. It is designed to works at an ambient temperature range 0-60C with a maximum pressure of 10 bar.
