Double-ported globe control valves type Z10

Valves type Z10 (previous name: 10000 DG) with a pressure-balanced plug are used as final executive elements in automatic and remote control systems. They are used to regulate the flow rate of liquids and gases in the chemical industry, metallurgy, shipbuilding etc.

They can be supplied without drives or with drives. The standard drives are diaphragm-spring pneumatic actuators manufactured by Zakładów Automatyki POLNA. S.A.

We can adjust the control valve to match your individual needs.

Non-catalogue products We can adjust these parameters to your individual needs. In such cases, please contact our technical support specialist. In the menu: “Non-catalogue version control valves” and “New products” we present the following examples.
  • wide range of nominal dimensions, DN15…300 for nominal pressures PN10…160; CL150; CL600
  • various materials of valve body cast and internal parts, adapted to specific working conditions
  • wide range of flow coefficients
  • reduction in aggressive and toxic media emissions to the environment through application of bonnet packings meeting the requirements of TA – LUFT
  • easy assembly and dismantling of valve internal parts for maintenance and service
  • high durability and reliability due to application of top-class materials and surface improvement processes (burnishing, stelliting, heat treatment, CrN coatings)
  • possibility of matching with P/R multi-spring actuators (basic option), P1/R1. Full reversibility of actuator operation and changing the spring range with no extra parts
  • optional fitting of pneumatic actuators with manual drive
  • possibility of performing diagnostics of “valve-actuator” system, due to application of smart electro-pneumatic positioners
  • high tightness of closure due to the application of soft valve seats (with PTFE seals in the whole range of flow coefficients
  • - same flow ratios and control characteristics for “hard” valve seats (metal-to-metal) and “soft” valve seats (metal-to-gasket)
  • reliable connection between actuator stem and valve, as well as between screwed in seat and body,
  • top-class flat and bonnet packings
  • wide range of electric actuators,
  • possibility of matching with 20 or NN type manual drives
  • possibility of special executions: for oxygen, hydrogen, acid gases containing H2S; for explosive atmospheres as per 94/9/EC – ATEX
  • competitive prices – as a result of a simple and functional design of valves and actuators, as well as applied materials
  • the design and production process meet the requirements of Quality Management System ISO 9001 and Directive 97/23/EC, and regulations of AD2000 Merkblatt, designated for installation on pipelines
