Spring To Close Hand Lever

The spring to close hand lever actuates the valve with simple efficiency and ensures that the operator can't walk away from an open valve. Another safety feature of this system is that the operator must operate it in two swift motions, pulling the handle out and then down to open the valve and take a sample. This simple design ensures that the valve cannot be opened inadvertently. The hand lever can also be locked by fitting a lock at the base of the handle to prevent unauthorized use.

It also features a stroke limiter on the top of the mechanism so that sample flow through the outlet can be regulated.

Recommended for:

  • Highly viscous chemicals

  • Low-pressure sampling

  • Sampling into a cylinder

For high temperature processes, we have the added option of a fin extension which serves a dual purpose. While it effectively dissipates the heat before it reaches the handle, it may also be required on piping with thick insulation, allowing operators access to the hand lever, hand wheel or pneumatic actuator.. This is fitted between the valve body and the hand lever and offers another layer of protection from thermal burns. These are rated for temperatures up to 250ºC (482ºF).
