Parker offers a large variety of throttle and butterfly valves for different purposes. Industrial hydraulic throttle valves feature an exact and reliable control of oil flows. The range includes proportional throttle valves in slip-in cartridge design and with SAE flange, as well as throttle check valves for subplate, sandwich plate and pipe mounting. Various sizes enable an extremely variable use. The high-response valves allow the precise control of high flows at maximum dynamics. Parker butterfly valves are robust, compact and enable frequent operation with very low torque.

The pilot operated 2-way high response valves series TDP provide a precise control of high flows at maximum dynamics. Typical applications for these slip-in cartridge proportional throttle valves are die cast, injection molding and hydraulic presses.

The proven 2-way proportional throttle valves series TDA feature a precise control of large oil flows for an efficient, reliable operation.

With flow rates up to 9500 l/min and fast response times, proportional throttle valves series TEA are predestined for injection molding and die cast applications. The directional valve integrated in the pilot circuit provides the safety function.

Parker double-throttle check valves series FM in sandwich design offer an easy configuration of stack systems and provide a very good price-performance ratio. They are optionally available with a cylindrical needle for fine adjustment in NG06 and NG10.

In these robust valves, the internal component used to shut off the flow is a segment of a sphere. This allows frequent operation with very low torque, no fluid retention areas and therefore excellent mechanical performance.

Parker digital amplifier modules series PCD00A-400 combine all necessary functions for the optimal operation of two proportional pressure/flow control valves.

Parker's 3-way high-response cartridge valves series TPQ provide high flow control at maximum dynamics. They are predestined for demanding applications like injection molding and die cast.

Parker electronic modules series PWDXXA-40* combine all necessary functions for the optimal operation of proportional directional control valves with position sensor or valves in closed loop systems.

Parker’s FC, FD series throttle check valves are designed for maximum flow rates.

2-way high-response valves series TEP in cartridge design base on the TDP range and provide a precise control of high flows at maximum dynamics. Additionally, TEP valves are equipped with a direction control valve for shutting off the pilot system.

Parker's throttle check valves series ZRD in sandwich design feature maximum flow rates up to 160l/min and enable an easy configuration of stack systems.

The series of active pilot operated 2/2 way throttle valves TDW enables fast and safe switching operations. The valves in cartridge design are supplied as one unit to ensure easy installation.

The new Parker 2-way high performance proportional throttle valves series TDC are characterized by a precise control of high flows at high dynamics. Typical applications for TDC slip-in cartridge valves are injection molding and hydraulic presses.

The new proportional cartridge throttle valves series TFP provide outstanding flow rates and minimized pressure losses. They control highest flows precise and with maximum dynamics in applications like die cast, hydraulic presses and injection molding

Proportional throttle valves series F5C with SAE61 flange allow to adjust the flow in proportion to the input signal.
