A valve arrangement having an insert assembly (11) receivable in a receptacle (10). The insert assembly includes valve elements for controlling fluid flow through the valve. These include a gate (40) and chamber valve seat members (52, 53). The insert is constructed so that it can be removed from and located in the receptacle. When located in the receptacle and in operation the gate is urged against one of the seat members so that a seal is formed between the seat and gate and between the seat and receptacle body. The gate (40) can be an expandable gate.

Valve with removable insert

Clamped body replacement tool

An improved clamp connector for securing ends of tubular members together in tight sealed relationship and including a pair of semicircular segments having lips to engage the opposite sides of abutting projections on the tubular members, a pressure responsive actuator to preload the segments on the projections, connecting studs between the segments which are loaded by the actuator and blocks of a preselected size to be positioned in supporting relationship to the actuator in its preload position to maintain such preload on the segments and studs after the fluid pressure on the actuator is released. A pressure responsive portion of the blocks allows their quick and positive release when desired.

Clamp connector

A valve mounting for securing a valve body between two spaced apart mounting members having hydraulic studs which are elongated by pressure for release of the clamping engagement of the valve body for its quick and easy installation and removal. A preferred form of the present invention includes the application of a plurality of valve modules connected to the exterior of an elongate block manifold body through the use of hydraulic studs to control the flow into one of the longitudinal passages extending through the manifold body.
