SMC VHK series finger valves

Despite continuous developments in the manufacturing sector, manually operated valves still have their place in production. While many plants desire upgrades and welcome more flexible solutions, manually operated valves still provide benefits and are still relevant for certain applications. These hard-working, robust valves offer both control and durability.

SMC’s VHK series of finger valves enable ease of operation and visibility. The valve direction clearly indicates whether the valve is open or closed (shut to open is counter-clockwise) and the classification of the knob by colour helps in distinguishing between 2-port valves (grey) and 3-port valves (blue). In addition, the series features a sturdy construction to ensure no leaks, thus saving energy.

The robust valves offer a poppet valve construction and can operate at a maximum pressure of 1 MPa and an operating vacuum pressure of -100 kPa. The series begins with a minimum tube diameter of 4 mm and accommodates air at temperatures of between 0 and 60°C.

In addition to the standard VHK 2- and 3-port finger valve options, SMC also offers a flame-resistant version for harsher environments.
