Abstract: A double-block and vent valve having an improved actuator mechanism to allow one part of a composite valve member to be lifted separately from another. The actuator mechanism overlies the valve housing and is connected to the two valve member parts via coaxial rod and tube members. Hold-down cams normally block the upward movement of the tube member to positively lock the upper valve member part against its seat when it is desired to lift only the lower valve member part. A pair of pivotal cams are spring-biased to this blocking position where they bear against lug means carried by the tube member. A small, horizontal, fluid-actuated cylinder pivots the hold-down cams to a non-interfering position whenever it is desired to lift only the upper valve member part or to lift the composite valve member.

Abstract: A safety device for a fluid operated tool features a throttle lever which is always freely movable but is normally rendered inoperable to effect tool actuation except in response to a consciously deliberate two step action wherein a first valve control must be actuated before an on-off valve controlling fluid flow may be operated by a second valve control in response to throttle lever operation to drive the on-off valve from a normally closed position to an open position establishing an open fluid flow condition for tool start-up.

Abstract: An erosion resistant control valve or adjustable choke has a body with a side inlet, an end outlet and a conical valve seat in alignment with the outlet.
